Explanation of the main modes / navigation buttons
5.Getting started
(1)Introduction
ln order to obtain a bend program for a product, the control offers the possibility to create a product drawing and calculate a valid bend sequence for the product. With this information, a product program is generated.
This is done with the following steps:
Go to the Products mode in the navigation panel and start a new product by tapping New Product.
Enter the product properties and start to draw a 2D product profile in the Drawing mode.
Check the tooling, modify or make a new set-up in the Tool Setup mode.
Use the Bend Sequence mode to determine the bend sequence by calculating it or manually modifying it upon your own idea’s.
When required modify the numerical CNC program via the Program mode.
Tap Auto and press the Start button in order to produce the programmed product.
(2) Preparations
Before product programming can be started, the following preparations must be made.
The correct material properties must have been programmed in the Materials library. You can find this on the Materials page in the Settings mode.
The correct tools must be programmed in the Tool Library. Tools are necessary to create a CNC program. You can find the libraries for the different types of tools in the Machine mode.
(3)Create a drawing
The control offers the functionality to create a drawing of the intended product. With this drawing application, tap Drawing in the navigation panel, a 2D profile or 3D product drawing is created. At this stage, there is no calculation of bends or dimensions: any profile or drawing can be created. The drawing method on the Touch screen control is based on:
Sketching
Value setting
Sketching
The product as well as tool shape Sketching can be done by tapping on the screen in the different directions the drawing must have. The application will follow the tapping with drawing a line between the indicated points. The last point of the design will show always a big red dot.
When the drawing dot is on the screen you can hold your finger on this position and move the finger across the screen to move the connected line in another required direction or make the line length longer. This method is the so-called ‘Dragging’ facility. The length and angle value will be visible on the screen and can be adjusted to be exact or close to the requested value.
Value Setting
Once the product or tool is drawn in the Sketching method the exact values of line lengths and angles can be optimized by the Value setting method. Just tap 2 times on the value of the line length or angle to change and the keyboard will pop-up. The value can be entered in 2 ways
of confirmation:
Enter function
Enter-Next function
The Enter function will close the keyboard after entering the value. The Enter-Next function will enter the value on the line or angle to change and the keyboard will remain opened for the next programming step. ln case the typed value is erroneous, the “undo” button right from the input field can be tapped to return to the original value or the backspace key on the keyboard to delete the last typed character.
Zoom Function
By pinching the screen with two fingers simultaneously one can zoom in and out on the drawing, tool or machine visualization. By spreading fingers the system will zoom-in, by bringing fingers nearer to each other the system will zoom-out.
Fit-To-Screen
In the command icons on the side of the screen you will find a Fit-To-Screen function. This can be used when the drawing size is not clear in picture. Just tap once and the complete drawing will be sized to fit the drawing screen.
Panning
With simultaneous touching of two fingers and dragging them over the screen (sliding in the same direction)one can pan the object in 3D view. In 2D a single finger will also enable panning.
Rotating
In 3D, rotating the product, tool or machine visualization, can be done with a single finger sliding over the screen.
More information about this can be found in chapter 3.
Features of the drawing tool
Graphical design of product shapes in 2D and 3D (if available)Scaled sheet thickness
Auto scaling
Horizontal and vertical projected dimensions can be entered Real scale tool design
Various machine shapes (press beams and tables)Changing of lengths and angles
Adding or deleting of bends
Special bend features can be applied Hemming bends can be programmed Bumping bends can be used for big radius
Existing products can be copied, changed and stored as a new product Closing dimension or highest precision tolerance selection
Connecting 2D programs for 3D-production
(4)Determine bend sequence
When the product drawing is completed, the control offers Tool setup mode to program the exact tool set-up as it is organized on the machine. After this you can select the Bend Sequence mode to determine and simulate the required bend sequence.
In the Bend Sequence mode, the control shows the product, the machine and the tools. In this menu the bend sequence can be programmed and checked visually. When a bend sequence has been determined, the CNC program can be generated.
More information about this can be found in chapters 4 and 5.
Bending sequence computation
Automatic computation for minimum production time.
Interactive bend sequence determination
Manual bend sequence determination
Collision visualization of product with tools and machine.
Free tool and machine shape selections
Assignments of turn times, back gauge speed etc.
Blank length computation
Production time indication Bending sequence simulation.
Programmable finger positions
(5)Numerical program
The Program menu gives access to the numerical program and values of the active product.
There are two possibilities to create a CNC program:
enter a numerical program, started via Products mode, tap New Program, step by step;
generate the program from the graphical bend simulation started via the Products mode, tap New Product, via the Drawing mode. (see: Drawing mode; product drawing).
lf the program is entered by hand, there is no collision check. All program values must be entered manually. The program depends on operator experience.
lf the program is generated from a graphical bend sequence, the program can be visualised during production. A generated program can be edited according to operation needs.
More information about this can be found in chapter 6.
When a drawing has been completed with a bend sequence, and the program is stored, the program is postprocessed and the numerical program becomes available.
The system automatically computes :
. Necessary force
Machine adjustments such as
Y-axis position
Decompression
x-axis position.
X-axis retract.
Y-opening.
R-axes.
Z-axes
Axes positions are calculated according to the machine configuration.
(6)The Auto menu and Manual menu, production modes
A product program can be executed via the Auto mode. In Automatic mode, a complete program can be executed bend after bend. ln the Auto mode the Step mode can be selected to have each bend started separately.
The Manual mode of the control is an independent production mode. In this mode, one bend can be programmed and executed. It is typically used to test the behavior of the bend system.
More information about this can be found in chapters 7 and 8.
(7)Back-up data, external storage
Both product and tool files can be stored externally. Depending on the configuration, these files can be stored on a network or on a USB stick. This facilitates a back-up of important data and the possibility to exchange files between Delem controls.
More information about this can be found in chapter 9.
6.Programming aids
(1)Help text
This control is equipped with an on-line Help function. When the Help-button in the navigation panel is pressed context sensitive help will be provided.
To activate a help window for a parameter tap the Help button in the navigation panel. A pop-up window appears with information on the active parameter.
This Help window contains the same information as the Operation manual. The help window can be used as follows:
You can scroll through the text sliding one finger in the desired direction. By tapping on the lower or upperpart of the screen Previous Page / Next Page can be used to browse through the help text.
The Index function helps to jump to the table of contents. Hyperlinks in the table help to directly navigate to the desired topic.
Tap End to close the Help window.
(2) Listbox functionality
Several parameters on the control have a limited number of possible values. When selecting such a parameter, by tapping the parameter line on the screen, the list of options will open up near the position where you tapped the line, and the desired value can be selected.
To undo the selection and the opened listbox, tapping outside the box will make it close without changing the selected parameter.
(3) Filter, live search, auto filter
ln some modes a list of entities is offered (products, tools, materials, etc.). An example of such a menu is the Products mode (product selection). To search a particular product or tool, the filter function can be used. Press the command button Filter, type a part of the ID in the enter field. Automatically the list is limited to those items that contain the typed part.
Multiple search parts can be separated by <space>.
To close an open filter screen use the keyboard-close button on the right side next to the keyboard.
Auto filter
ln addition to the filter function the column headers of eg. the tool selection tables and the product selection table have ‘auto-filter ‘functionality.
When tapping the column header one can sort the list based on that specific column. The triangle in the header is shown as an indication of the sort order.
When tapping a header with auto-filter functionality a list box will be shown automatically offering the possible options for filtering, derived from the available entries in that column .E.g.
when using this in a die selection, the V-opening can be filtered to the desired value as searched for. The list will only show dies complying the set filter.
Filters can be switched of in a similar way. The list also offers a remove filter function.
(4) Navigation
Within some modes, the program screens are divided into tabs.
The tabs can easily be selected by just tapping them. When a tab is not completely visible or not visible at all, just by dragging the tab row horizontally, the desired tab can be “pulled” in sight and be selected.
(5)Text input and editing
The cursor can be used to enter a specific value or text within an existing input. Just tap at the desired position to do so. The cursor will appear and input will be added there.
E.g. in Edit notes, where multiple lines can be entered Enter is used for linefeed. Cut, Copy and Paste are offered on the keyboard for editing convenience. Undo and Redo can also be used within this editor.
The keyboard can be shown or hidden in this multiline editor using the arrow key in the lower left corner.
() Typing alphanumeric characters vs. Special characters
Both alphanumeric characters and special characters can be used throughout the control. A full on-screen alphanumerical keyboard will pop up when required.
When editing a field which is pure numeric, the alphanumeric characters will be “greyed-out” and only the numerical keypad can be used. For fields which enable to use alphanumerical
strings, the keyboard is completely available. Special characters as ? % – can be found using the special character button on the left-lower side of the keyboard.
Special characters (like a,a,,a,a,a, ce) are supported by the on screen keyboard by keeping a character (like ‘a’) pressed.
(7) Calculator
The CNC control is providing a “desktop calculator” available for the operator.
At the top of the screen the calculator icon can be used to switch to calculator functionality.
The keyboard area provides calculator functions which can be used autonomously. Standard functions (add ,subtract, multiply and devide) including percentage, square root, square and memory functions are available.
ln case calculations should use parameter values as an input, and results as an output, one can switch to the calculator from the parameter entry. This will bring the parameter value to the calculator, and the result back to the input line.
No cutting or pasting is necessary. Only when entering and confirming the calculated value in the parameter entry line, it will be used forward.
(8)Messages centre
When messages are displayed coming from PLC, Safety systems, LUAPs or the Sequencer， these messages can be ‘send to the ‘Messages centre’. When a message is displayed simultaneously the message Centre symbol is shown in the top row of the page header, next to eg. the calculator and keylock symbol. When tapping this message centre symbol the messages are taken from the screen, giving way for normal programming and editing.
When tapping again the actual messages are shown.
When messages are in the background, the message centre symbol has an extra indicator to show new incoming messages which are not yet shown.
(9)Network
The CNC control is equipped with a network interface. The network function offers the operators the possibility to import product files directly from the network directories or to export the finished product files to the network directory
Chapter 9 about backup/restore in Settings mode contains more information about networking possibilities.
(10) Keylock function
To prevent for changes to products or programs, the keylock function offers the possibility to lock the control.
There are two levels of locking the control. Program Lock and Machine Lock. ln Program Lock, only a product can be selected and executed in Automatic mode. ln Machine Lock, the machine is locked and the control can not be used.
To lock a control just tap the lock symbol in the top of the screen. Depending on the code which is used, the control will be in Program Lock or Machine Lock. Program Lock will show a closed lock in grey. Machine lock will show the same lock but colored (red).
(11) OEM function panel
Depending on machine manufacturers implementation, the upper right corner of the screen can be used for special indicators.
To access functions related to those indicators, the OEM function panel can be opened by tapping this corner of the screen.
(12) Software versions
The version of the software in your control is displayed at the System Information tab in the Machine menu.
Products, the product library
In Products mode an overview is given of the program library on the control. In this mode a product program can be selected (loaded). After that a program can be modified or executed.
Each item in the list consists of a thumbnail of the graphical product (for numerical programs a symbol is shown), its Product lD , the Product Description, the Number of bends in the product, what kind of product it is(Type) and the Date it was last used or modified.
The Type indication of the product shows following types of products:
(2)Product selection
To select a product a single tap will do. The product will be selected and loaded into the memory. From here production can be started by tapping Auto. Also navigation can start
through the Products Drawing (if existing), its Tool Setup, the Bend Sequence and the numerical Program of the product.
(3)New Product, starting a new graphical product
To start a new graphical product tap New Product.
After New Product is chosen, the programming of a new product starts with its general details like Product ID. Thickness and Material.
(4)New Program, starting a numerical program
To start a new numerical program tap New Program.
After New Program is chosen, the programming starts with its general details like e.g. Product lD, Thickness and Material.
(5)Views
To view the products as a simple list, or completely graphical, the View function can be used. By tapping View one of the three view modes can be selected.
(6)Edit, Copying and Deleting a product or program
To delete a product in the Products mode select a product by tapping it. It will be selected.
After that tap Edit and use Delete. To finally delete it confirm the question. To delete all products and programs at once, tap Delete All.
To copy a product select a product or program and tap Edit and use Copy. After this the name of the product can be programmed and the copy will be done. The product will appear in the same directory. The copied product will be an exact copy including tool setup and bend sequence if available.
(7) Product Rename and Move
Products can also be moved and renamed. This can be done in one single step: Move moves a product to a new directory, Rename allows the user to give it a new name within the same directory.
To move or rename a product select a product or program and tap Edit and choose Move or Rename from the list. For Rename a new name can be given. The product will appear in the same directory. For move a new location can be selected. The copied product will be an exact copy including tool setup and bend sequence if available.
(8)Product Lock/Unlock
The product Lock/Unlock function provides a simple method to prevent accidental changes to finished programs or products. In this way products which have been tuned and found to be good cannot be changed unless the product is unlocked.
When tapping on Edit the Lock Product / Unlock Product feature can be switched for each product or program.
(9)Filter function
To make finding products easier the filter function enables live searches through-out the Products mode.
When tapping Filter, the filter screen will show. By typing the desired filter string, optionally devided by spaces, the live search will start.
Optionally a different view can be selected. Also the specific property on which the filter is applied can be changed by using Selection.
Selections can be done on Product lD, Product Description, Type, Thickness, Length or Date. You can either enter a complete name or number or only a part of it. If you enter part of a name and this part occurs in several product names, the control will show all product names that contain that part. lt is also possible to enter a combination of name and number.
See also section 1.6.3 about Filtering and ‘Live search’.
(10) Change directory
To change to a different product directory, or to add a new product directory, tap Change Directory. When an obsolete directory must be removed, select the directory and tap Remove
Directory. When a desired directory is reached, tap Select to jump back to the Products screen which will show all products in the directory. The active local directory name is displayed in the header.
(11) Network product selection
When a network directory has been mounted in the control this mounted directory can be found under Network. Network is available next to the Product directory when using change directory. The name of the mounted drive indicates availability for product selection and
storage.
The network directories can be navigated thru in the directory browser. Directories can be selected, added and removed and products can be selected. When a desired directory is reached, tap Select to jump back to the Products screen which will show all products in the directory. The network directory is now the active local directory. Its name is displayed in the header of the screen.
When you leave the product selection menu the control remembers the active subdirectory and the active product (if a product was selected) until another directory or product is selected.
While working with a “read-only” network, or when the network connection is interrupted, the product will be saved in subdirectory “Recovered”. This can be found as a subdirectory under Products.
By tapping the Refresh button (on View) in Products mode the product library that is displayed on the screen is refreshed, which can be useful when working from a network location.
2.The DXF import option
An alternative for drawing the desired product in the control, the control can also import an externally
generated CAD-system output file. This chapter will explain the use of the DXF converter to import DXF files and its functionality.
The DXF import option is started with the command button above New Product. Import DXF opens a files election browser to select the DXF file.
Files can be located on eg. a USB stick or on the network directory. One can browse to the location and select the file.
For the DXF file to be imported it is advised to create the original drawing as accurate as possible .Bend lines should be connected to contour lines to obtain an accurate product drawing. If this is not the case, the DXF Converter can correct small errors.
After selecting the DXF file the DXF import function window will open showing the DXF file. If this is with layer selection on, the drawing will be dashed, since no line is yet assigned to what it means.
(1) Product drawing dimensions
The drawing file can be organised in two ways:. projection dimensions;
. cutting dimensions.
These ways are described in the following subparagraphs.
During operation in the DXF converter, it is possible to switch between cutting dimensions and projection dimensions. This can be done in the DXF conversion settings.
Projection dimensions
ln this situation all product sides and bend lines have the length of the resulting product. The drawing does not represent the real size of the sheet that must be bent, but is merely a representation of how the sheet is to be organised into bends and surfaces. When such a
drawing is loaded and converted, the converter will construct a product drawing with exactly the same sizes as are present in the original drawing .Later on additional information is added about material, sheet thickness and product dimensions. It is left to the control to create a CNC program with proper axes positions that will result in a product as intended.
For a proper conversion, the assignment of specific product properties to lines in the DXF is important.
Depending on the content of the DXF, the bendlines, contour and additional text information can be assigned layer by layer. ln case layer selection is set off, the bendlines are being searched for automatically.
Bend line information
With the bendlines the angle information can be defined via text near the line. The text labels, to be configured in Settings: Labels ,can be used as follws:
. Default: normal air bending with a positive or negative value
.Hemming: an H followed by a positive or negative value of the pre-bend angle. Radius: an R followed by the value of the radius.
Definition:
positive value: the flange bends upwards, negative value: the flange bends downwards.
Product information
Beside the actual product drawing a DXF drawing can contain other information, such as manufacturer name, dimension lines, product description etc. If this information is organised in other layers than the product
drawing then this information can be filtered out by selecting only certain layers for conversion. Otherwise, it possible to remove unnecessary information in the converter program before conversion of the drawing is started.
Layer selection
Depending on the DXF import settings, which can be entered from the mainscreen, layer selection can be seton or off.
ln case of layer selection on, the layer property list visualisation can be switched. The buttons in the left top corner enable this choice. Following paragraphs describe the difference between
Layer selection switched on and Layer selection switched off.
(3)Conversion
when the assignments have been set properly, conversion can be executed by tapping the Convert button.
The conversion preview will be shown when there are warnings or errors.
During conversion the DXF drawing is represented by lines like contour line, bend line and inside contourlines .Colors indicate the property for the line conversion. The lines of the product drawing will have different colours after the conversion .Every colour has its own meaning:
Blue: Contour line, this line is a part of the outer contour of the product.
Red :Bend line ,this line is a bending.
Green: Inside contour, this line is a part of the inner contour of the product..
Black: Assigned texts will be shown in black.
(4)Converting cutting dimensions, with bend allowance info
At the last stage of converting a DXF with cutting dimensions, the bend allowance which has been used during unfolding, needs to be reused in the conversion.
Therefore the conversion of cutting dimensions will always use the bend allowance table of the control and it will check if for all bends bend allowance information is available.
In case there is just one set of bend allowance parameters available for each bend, this will be used. The bend allowance pop-up will show the angles from the product with the found bend allowance. lf more entries in the table can be valid, one needs to select the appropriate bend allowance line. The prefered and calculated radius can be helpful in this selection.
Adding Bend Allowance information manually
ln case the bend allowance information is given with the DXF cutting dimension drawing, included in the DXF or as separate info, there is the possibility to manually enter this information.
When a DXF is imported and the bend allowance value per bend is included (based on the bendline info) these values are imported and used with the desired bend. The control will use this as an input which overules the bend allowance calculation or table search of the control.
lf this information is entered during the DXF conversion, this will work equivalently, bypassing the controls calculation or table search.
lf the desired bend allowance information is not present from the table, one can also manually add the information just before actual converting. In case the bend allowance is not given before or during the DXF conversion this will be automatically prompted. One can select either to select from excisting entries from the bend allowance table, or enter bend allowance just for this conversion.
To enable the function of programming bend allowance information in the Drawing function of the control(bend property) this needs to be switched on in the product properties. This is automatically done in case of importing.
(5)DXF Settings
In the DXF converter settings the conversion parameters can be configured. lt is possible to store multiple settingsfiles for specific drawing types. Save as and load functions are available.
Conversion parameters
3.The 3D import function (Profile-T3D offline only)
An alternative for drawing the desired product in the application is to import an externally generated CAD-system file. With the 3D import function Profile-T3D can import the generic .IGES and .STEP files.
This chapter will explain the use of the 3D import functionality for. lGES and .STEP files.(This functionality is solely available in Profile-T3D)
The 3D import function is started via the Import command button above New Product. lmport 3D opens a file selection browser to select an .IGES or .STEP file.
The conversion can be started by tapping Convert. This will start the interpretation of the 3Ddesign into a product with bendlines and sheetmetal specific characteristics.
The application will show the product with the designated bendlines.
ln case the converter does not find any imperfections the conversion is previewed and one can finalize the conversion with tapping Accept.
From here the product is converted and shown in Drawing mode.
One can continue with tool selection and bend sequence programming.
The 3D CAD file requirements
For the .IGES and .STEP files to be imported it is important to meet the constraints for sheet metal product designs. The constraints are available upon request at Delem.
The 3D file to be imported must of course be generated with the objective to design a sheet metal part which can be processed on a press brake.
4.The DXF contour export option
As part of the DXF-option the Export DXF function, on Edit in Products mode and on Transfer(Profile-T), enables the export of any product including the bend deductions as a contour. This contour is stored as a DXF and holds the cutting dimensions.
Product drawing
To start a new product drawing, choose New Product in the product library
When a new product drawing is started a screen with general product properties appears.First these properties, general data, should be set before starting with the product drawing.
(1)Add Notes
When Edit Notes has been pressed, a new window appears in which you can edit the text about the current product. The possible characters are displayed on the keyboard.

Explanation of the main modes / navigation buttons
5.Getting started
(1)Introduction
ln order to obtain a bend program for a product, the control offers the possibility to create a product drawing and calculate a valid bend sequence for the product. With this information, a product program is generated.
This is done with the following steps:
Go to the Products mode in the navigation panel and start a new product by tapping New Product.
Enter the product properties and start to draw a 2D product profile in the Drawing mode.
Check the tooling, modify or make a new set-up in the Tool Setup mode.
Use the Bend Sequence mode to determine the bend sequence by calculating it or manually modifying it upon your own idea’s.
When required modify the numerical CNC program via the Program mode.
Tap Auto and press the Start button in order to produce the programmed product.
(2) Preparations
Before product programming can be started, the following preparations must be made.
The correct material properties must have been programmed in the Materials library. You can find this on the Materials page in the Settings mode.
The correct tools must be programmed in the Tool Library. Tools are necessary to create a CNC program. You can find the libraries for the different types of tools in the Machine mode.
(3)Create a drawing
The control offers the functionality to create a drawing of the intended product. With this drawing application, tap Drawing in the navigation panel, a 2D profile or 3D product drawing is created. At this stage, there is no calculation of bends or dimensions: any profile or drawing can be created. The drawing method on the Touch screen control is based on:
Sketching
Value setting
Sketching
The product as well as tool shape Sketching can be done by tapping on the screen in the different directions the drawing must have. The application will follow the tapping with drawing a line between the indicated points. The last point of the design will show always a big red dot.
When the drawing dot is on the screen you can hold your finger on this position and move the finger across the screen to move the connected line in another required direction or make the line length longer. This method is the so-called ‘Dragging’ facility. The length and angle value will be visible on the screen and can be adjusted to be exact or close to the requested value.
Value Setting
Once the product or tool is drawn in the Sketching method the exact values of line lengths and angles can be optimized by the Value setting method. Just tap 2 times on the value of the line length or angle to change and the keyboard will pop-up. The value can be entered in 2 ways
of confirmation:
Enter function
Enter-Next function
The Enter function will close the keyboard after entering the value. The Enter-Next function will enter the value on the line or angle to change and the keyboard will remain opened for the next programming step. ln case the typed value is erroneous, the “undo” button right from the input field can be tapped to return to the original value or the backspace key on the keyboard to delete the last typed character.
Zoom Function
By pinching the screen with two fingers simultaneously one can zoom in and out on the drawing, tool or machine visualization. By spreading fingers the system will zoom-in, by bringing fingers nearer to each other the system will zoom-out.
Fit-To-Screen
In the command icons on the side of the screen you will find a Fit-To-Screen function. This can be used when the drawing size is not clear in picture. Just tap once and the complete drawing will be sized to fit the drawing screen.
Panning
With simultaneous touching of two fingers and dragging them over the screen (sliding in the same direction)one can pan the object in 3D view. In 2D a single finger will also enable panning.
Rotating
In 3D, rotating the product, tool or machine visualization, can be done with a single finger sliding over the screen.
More information about this can be found in chapter 3.

(5)Numerical program
The Program menu gives access to the numerical program and values of the active product.
There are two possibilities to create a CNC program:
enter a numerical program, started via Products mode, tap New Program, step by step;
generate the program from the graphical bend simulation started via the Products mode, tap New Product, via the Drawing mode. (see: Drawing mode; product drawing).
lf the program is entered by hand, there is no collision check. All program values must be entered manually. The program depends on operator experience.
lf the program is generated from a graphical bend sequence, the program can be visualised during production. A generated program can be edited according to operation needs.
More information about this can be found in chapter 6.
When a drawing has been completed with a bend sequence, and the program is stored, the program is postprocessed and the numerical program becomes available.
The system automatically computes :
. Necessary force
Machine adjustments such as
Y-axis position
Decompression
x-axis position.
X-axis retract.
Y-opening.
R-axes.
Z-axes
Axes positions are calculated according to the machine configuration.
(6)The Auto menu and Manual menu, production modes
A product program can be executed via the Auto mode. In Automatic mode, a complete program can be executed bend after bend. ln the Auto mode the Step mode can be selected to have each bend started separately.
The Manual mode of the control is an independent production mode. In this mode, one bend can be programmed and executed. It is typically used to test the behavior of the bend system.
More information about this can be found in chapters 7 and 8.
(7)Back-up data, external storage
Both product and tool files can be stored externally. Depending on the configuration, these files can be stored on a network or on a USB stick. This facilitates a back-up of important data and the possibility to exchange files between Delem controls.
More information about this can be found in chapter 9.
6.Programming aids
(1)Help text
This control is equipped with an on-line Help function. When the Help-button in the navigation panel is pressed context sensitive help will be provided.
To activate a help window for a parameter tap the Help button in the navigation panel. A pop-up window appears with information on the active parameter.
This Help window contains the same information as the Operation manual. The help window can be used as follows:
You can scroll through the text sliding one finger in the desired direction. By tapping on the lower or upperpart of the screen Previous Page / Next Page can be used to browse through the help text.
The Index function helps to jump to the table of contents. Hyperlinks in the table help to directly navigate to the desired topic.
Tap End to close the Help window.
(2) Listbox functionality
Several parameters on the control have a limited number of possible values. When selecting such a parameter, by tapping the parameter line on the screen, the list of options will open up near the position where you tapped the line, and the desired value can be selected.
To undo the selection and the opened listbox, tapping outside the box will make it close without changing the selected parameter.
(3) Filter, live search, auto filter
ln some modes a list of entities is offered (products, tools, materials, etc.). An example of such a menu is the Products mode (product selection). To search a particular product or tool, the filter function can be used. Press the command button Filter, type a part of the ID in the enter field. Automatically the list is limited to those items that contain the typed part.
Multiple search parts can be separated by <space>.
To close an open filter screen use the keyboard-close button on the right side next to the keyboard.
Auto filter
ln addition to the filter function the column headers of eg. the tool selection tables and the product selection table have ‘auto-filter ‘functionality.
When tapping the column header one can sort the list based on that specific column. The triangle in the header is shown as an indication of the sort order.
When tapping a header with auto-filter functionality a list box will be shown automatically offering the possible options for filtering, derived from the available entries in that column .E.g.
when using this in a die selection, the V-opening can be filtered to the desired value as searched for. The list will only show dies complying the set filter.
Filters can be switched of in a similar way. The list also offers a remove filter function.
(4) Navigation
Within some modes, the program screens are divided into tabs.
The tabs can easily be selected by just tapping them. When a tab is not completely visible or not visible at all, just by dragging the tab row horizontally, the desired tab can be “pulled” in sight and be selected.
(5)Text input and editing
The cursor can be used to enter a specific value or text within an existing input. Just tap at the desired position to do so. The cursor will appear and input will be added there.
E.g. in Edit notes, where multiple lines can be entered Enter is used for linefeed. Cut, Copy and Paste are offered on the keyboard for editing convenience. Undo and Redo can also be used within this editor.
The keyboard can be shown or hidden in this multiline editor using the arrow key in the lower left corner.
() Typing alphanumeric characters vs. Special characters
Both alphanumeric characters and special characters can be used throughout the control. A full on-screen alphanumerical keyboard will pop up when required.
When editing a field which is pure numeric, the alphanumeric characters will be “greyed-out” and only the numerical keypad can be used. For fields which enable to use alphanumerical
strings, the keyboard is completely available. Special characters as ? % – can be found using the special character button on the left-lower side of the keyboard.
Special characters (like a,a,,a,a,a, ce) are supported by the on screen keyboard by keeping a character (like ‘a’) pressed.
(7) Calculator
The CNC control is providing a “desktop calculator” available for the operator.
At the top of the screen the calculator icon can be used to switch to calculator functionality.
The keyboard area provides calculator functions which can be used autonomously. Standard functions (add ,subtract, multiply and devide) including percentage, square root, square and memory functions are available.
ln case calculations should use parameter values as an input, and results as an output, one can switch to the calculator from the parameter entry. This will bring the parameter value to the calculator, and the result back to the input line.
No cutting or pasting is necessary. Only when entering and confirming the calculated value in the parameter entry line, it will be used forward.
(8)Messages centre
When messages are displayed coming from PLC, Safety systems, LUAPs or the Sequencer， these messages can be ‘send to the ‘Messages centre’. When a message is displayed simultaneously the message Centre symbol is shown in the top row of the page header, next to eg. the calculator and keylock symbol. When tapping this message centre symbol the messages are taken from the screen, giving way for normal programming and editing.
When tapping again the actual messages are shown.
When messages are in the background, the message centre symbol has an extra indicator to show new incoming messages which are not yet shown.
(9)Network
The CNC control is equipped with a network interface. The network function offers the operators the possibility to import product files directly from the network directories or to export the finished product files to the network directory
Chapter 9 about backup/restore in Settings mode contains more information about networking possibilities.
(10) Keylock function
To prevent for changes to products or programs, the keylock function offers the possibility to lock the control.
There are two levels of locking the control. Program Lock and Machine Lock. ln Program Lock, only a product can be selected and executed in Automatic mode. ln Machine Lock, the machine is locked and the control can not be used.
To lock a control just tap the lock symbol in the top of the screen. Depending on the code which is used, the control will be in Program Lock or Machine Lock. Program Lock will show a closed lock in grey. Machine lock will show the same lock but colored (red).
(11) OEM function panel
Depending on machine manufacturers implementation, the upper right corner of the screen can be used for special indicators.
To access functions related to those indicators, the OEM function panel can be opened by tapping this corner of the screen.
(12) Software versions
The version of the software in your control is displayed at the System Information tab in the Machine menu.
Products, the product library
- Introduction
- The main view
In Products mode an overview is given of the program library on the control. In this mode a product program can be selected (loaded). After that a program can be modified or executed.
Each item in the list consists of a thumbnail of the graphical product (for numerical programs a symbol is shown), its Product lD , the Product Description, the Number of bends in the product, what kind of product it is(Type) and the Date it was last used or modified.
The Type indication of the product shows following types of products:
(2)Product selection
To select a product a single tap will do. The product will be selected and loaded into the memory. From here production can be started by tapping Auto. Also navigation can start
through the Products Drawing (if existing), its Tool Setup, the Bend Sequence and the numerical Program of the product.
(3)New Product, starting a new graphical product
To start a new graphical product tap New Product.
After New Product is chosen, the programming of a new product starts with its general details like Product ID. Thickness and Material.
(4)New Program, starting a numerical program
To start a new numerical program tap New Program.
After New Program is chosen, the programming starts with its general details like e.g. Product lD, Thickness and Material.
(5)Views
To view the products as a simple list, or completely graphical, the View function can be used. By tapping View one of the three view modes can be selected.
(6)Edit, Copying and Deleting a product or program
To delete a product in the Products mode select a product by tapping it. It will be selected.
After that tap Edit and use Delete. To finally delete it confirm the question. To delete all products and programs at once, tap Delete All.
To copy a product select a product or program and tap Edit and use Copy. After this the name of the product can be programmed and the copy will be done. The product will appear in the same directory. The copied product will be an exact copy including tool setup and bend sequence if available.
(7) Product Rename and Move
Products can also be moved and renamed. This can be done in one single step: Move moves a product to a new directory, Rename allows the user to give it a new name within the same directory.
To move or rename a product select a product or program and tap Edit and choose Move or Rename from the list. For Rename a new name can be given. The product will appear in the same directory. For move a new location can be selected. The copied product will be an exact copy including tool setup and bend sequence if available.
(8)Product Lock/Unlock
The product Lock/Unlock function provides a simple method to prevent accidental changes to finished programs or products. In this way products which have been tuned and found to be good cannot be changed unless the product is unlocked.
When tapping on Edit the Lock Product / Unlock Product feature can be switched for each product or program.
(9)Filter function
To make finding products easier the filter function enables live searches through-out the Products mode.
When tapping Filter, the filter screen will show. By typing the desired filter string, optionally devided by spaces, the live search will start.
Optionally a different view can be selected. Also the specific property on which the filter is applied can be changed by using Selection.
Selections can be done on Product lD, Product Description, Type, Thickness, Length or Date. You can either enter a complete name or number or only a part of it. If you enter part of a name and this part occurs in several product names, the control will show all product names that contain that part. lt is also possible to enter a combination of name and number.
See also section 1.6.3 about Filtering and ‘Live search’.
(10) Change directory
To change to a different product directory, or to add a new product directory, tap Change Directory. When an obsolete directory must be removed, select the directory and tap Remove
Directory. When a desired directory is reached, tap Select to jump back to the Products screen which will show all products in the directory. The active local directory name is displayed in the header.
(11) Network product selection
When a network directory has been mounted in the control this mounted directory can be found under Network. Network is available next to the Product directory when using change directory. The name of the mounted drive indicates availability for product selection and
storage.
The network directories can be navigated thru in the directory browser. Directories can be selected, added and removed and products can be selected. When a desired directory is reached, tap Select to jump back to the Products screen which will show all products in the directory. The network directory is now the active local directory. Its name is displayed in the header of the screen.
When you leave the product selection menu the control remembers the active subdirectory and the active product (if a product was selected) until another directory or product is selected.
While working with a “read-only” network, or when the network connection is interrupted, the product will be saved in subdirectory “Recovered”. This can be found as a subdirectory under Products.
By tapping the Refresh button (on View) in Products mode the product library that is displayed on the screen is refreshed, which can be useful when working from a network location.
2.The DXF import option
An alternative for drawing the desired product in the control, the control can also import an externally
generated CAD-system output file. This chapter will explain the use of the DXF converter to import DXF files and its functionality.
The DXF import option is started with the command button above New Product. Import DXF opens a files election browser to select the DXF file.
Files can be located on eg. a USB stick or on the network directory. One can browse to the location and select the file.
For the DXF file to be imported it is advised to create the original drawing as accurate as possible .Bend lines should be connected to contour lines to obtain an accurate product drawing. If this is not the case, the DXF Converter can correct small errors.
After selecting the DXF file the DXF import function window will open showing the DXF file. If this is with layer selection on, the drawing will be dashed, since no line is yet assigned to what it means.
(1) Product drawing dimensions
The drawing file can be organised in two ways:. projection dimensions;
. cutting dimensions.
These ways are described in the following subparagraphs.
During operation in the DXF converter, it is possible to switch between cutting dimensions and projection dimensions. This can be done in the DXF conversion settings.
Projection dimensions
ln this situation all product sides and bend lines have the length of the resulting product. The drawing does not represent the real size of the sheet that must be bent, but is merely a representation of how the sheet is to be organised into bends and surfaces. When such a
drawing is loaded and converted, the converter will construct a product drawing with exactly the same sizes as are present in the original drawing .Later on additional information is added about material, sheet thickness and product dimensions. It is left to the control to create a CNC program with proper axes positions that will result in a product as intended.
For a proper conversion, the assignment of specific product properties to lines in the DXF is important.
Depending on the content of the DXF, the bendlines, contour and additional text information can be assigned layer by layer. ln case layer selection is set off, the bendlines are being searched for automatically.
Bend line information
With the bendlines the angle information can be defined via text near the line. The text labels, to be configured in Settings: Labels ,can be used as follws:
. Default: normal air bending with a positive or negative value
.Hemming: an H followed by a positive or negative value of the pre-bend angle. Radius: an R followed by the value of the radius.
Definition:
positive value: the flange bends upwards, negative value: the flange bends downwards.
Product information
Beside the actual product drawing a DXF drawing can contain other information, such as manufacturer name, dimension lines, product description etc. If this information is organised in other layers than the product
drawing then this information can be filtered out by selecting only certain layers for conversion. Otherwise, it possible to remove unnecessary information in the converter program before conversion of the drawing is started.
Layer selection
Depending on the DXF import settings, which can be entered from the mainscreen, layer selection can be seton or off.
ln case of layer selection on, the layer property list visualisation can be switched. The buttons in the left top corner enable this choice. Following paragraphs describe the difference between
Layer selection switched on and Layer selection switched off.
(3)Conversion
when the assignments have been set properly, conversion can be executed by tapping the Convert button.
The conversion preview will be shown when there are warnings or errors.
During conversion the DXF drawing is represented by lines like contour line, bend line and inside contourlines .Colors indicate the property for the line conversion. The lines of the product drawing will have different colours after the conversion .Every colour has its own meaning:
Blue: Contour line, this line is a part of the outer contour of the product.
Red :Bend line ,this line is a bending.
Green: Inside contour, this line is a part of the inner contour of the product..
Black: Assigned texts will be shown in black.
(4)Converting cutting dimensions, with bend allowance info
At the last stage of converting a DXF with cutting dimensions, the bend allowance which has been used during unfolding, needs to be reused in the conversion.
Therefore the conversion of cutting dimensions will always use the bend allowance table of the control and it will check if for all bends bend allowance information is available.
In case there is just one set of bend allowance parameters available for each bend, this will be used. The bend allowance pop-up will show the angles from the product with the found bend allowance. lf more entries in the table can be valid, one needs to select the appropriate bend allowance line. The prefered and calculated radius can be helpful in this selection.
Adding Bend Allowance information manually
ln case the bend allowance information is given with the DXF cutting dimension drawing, included in the DXF or as separate info, there is the possibility to manually enter this information.
When a DXF is imported and the bend allowance value per bend is included (based on the bendline info) these values are imported and used with the desired bend. The control will use this as an input which overules the bend allowance calculation or table search of the control.
lf this information is entered during the DXF conversion, this will work equivalently, bypassing the controls calculation or table search.
lf the desired bend allowance information is not present from the table, one can also manually add the information just before actual converting. In case the bend allowance is not given before or during the DXF conversion this will be automatically prompted. One can select either to select from excisting entries from the bend allowance table, or enter bend allowance just for this conversion.
To enable the function of programming bend allowance information in the Drawing function of the control(bend property) this needs to be switched on in the product properties. This is automatically done in case of importing.
(5)DXF Settings
In the DXF converter settings the conversion parameters can be configured. lt is possible to store multiple settingsfiles for specific drawing types. Save as and load functions are available.
Conversion parameters
3.The 3D import function (Profile-T3D offline only)
An alternative for drawing the desired product in the application is to import an externally generated CAD-system file. With the 3D import function Profile-T3D can import the generic .IGES and .STEP files.
This chapter will explain the use of the 3D import functionality for. lGES and .STEP files.(This functionality is solely available in Profile-T3D)
The 3D import function is started via the Import command button above New Product. lmport 3D opens a file selection browser to select an .IGES or .STEP file.
- Conversion
The conversion can be started by tapping Convert. This will start the interpretation of the 3Ddesign into a product with bendlines and sheetmetal specific characteristics.
The application will show the product with the designated bendlines.
ln case the converter does not find any imperfections the conversion is previewed and one can finalize the conversion with tapping Accept.
From here the product is converted and shown in Drawing mode.
One can continue with tool selection and bend sequence programming.
The 3D CAD file requirements
For the .IGES and .STEP files to be imported it is important to meet the constraints for sheet metal product designs. The constraints are available upon request at Delem.
The 3D file to be imported must of course be generated with the objective to design a sheet metal part which can be processed on a press brake.
4.The DXF contour export option
As part of the DXF-option the Export DXF function, on Edit in Products mode and on Transfer(Profile-T), enables the export of any product including the bend deductions as a contour. This contour is stored as a DXF and holds the cutting dimensions.
Product drawing
To start a new product drawing, choose New Product in the product library
When a new product drawing is started a screen with general product properties appears.First these properties, general data, should be set before starting with the product drawing.
(1)Add Notes
When Edit Notes has been pressed, a new window appears in which you can edit the text about the current product. The possible characters are displayed on the keyboard.
