5. Getting started

(1)Introduction

In 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.

In 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 simultaeously one can zoom in and out on the drawing, tool or machine visualisation. 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 draging 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 visualisation, can be done with a single finger sliding over the screern.

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 (pressbeams 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 organised 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, backgauge 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).


If the program is entered by hand, there is no collision check. All program values must be entered manually. The program depends on operator experience.

If 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 post processed 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. In 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 behaviour 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.

DA-69T Operation Manual

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.


DA-69T Operation Manual

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 upper part 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.

(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.

DA-69T Operation Manual

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

In 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>.

DA-69T Operation Manual

To close an open filter screen use the keyboard-close button on the right side next to the keyboard.


Auto filter

In 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.

DA-69T Operation Manual

(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.

DA-69T Operation Manual

The keyboard can be shown or hidden in this multiline editor using the arrow key in the lower left corner.

(6) 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.

DA-69T Operation Manual

Special characters (like á, à, â, ã, ä, å, æ) are supported by the on screen keyboard by keeping a character (like ‘a’) pressed.

DA-69T Operation Manual

(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.

DA-69T Operation Manual


In 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 required network directory

DA-69T Operation Manual

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.

• In Program Lock, only a product can be selected and executed in Automatic mode.

• In 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 wil show a closed lock in grey. Machine lock will show the same lock but colored (red).

(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.

DA-69T Operation Manual


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 interupted, 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 file selection browser to select the DXF file.

DA-69T Operation Manual

Files can be located on eg. a USB stick or on the network directory. One can browse to the location and select the file.

DA-69T Operation Manual


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.

DA-69T Operation Manual

(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

In 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.

DA-69T Operation Manual

(2) Bendlines and Layer selection with Line assignment

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. In 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 set on or off. 

In 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 contour lines. 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.

DA-69T Operation Manual

(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. If 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.

DA-69T Operation Manual


Adding Bend Allowance information manually

In 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.


If this information is entered during the DXF conversion, this will work equivalently, bypassing the controls calculation or table search.

If 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. It 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.IGES 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. Import 3D opens a file selection browser to select an .IGES or .STEP file.

DA-69T Operation Manual

(1) Conversion

DA-69T Operation Manual

The conversion can be started by tapping Convert. This will start the interpretation of the 3D design into a product with bendlines and sheetmetal specific characteristics.

The application will show the product with the designated bendlines.

DA-69T Operation Manual


In 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.

DA-69T Operation Manual


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.

6. Station selection and repositioning

The third Tool Setup view is the Station view. In Station view the complete toolstations are highlighted when selected, and can be repositioned by programming an alternate position or dragging to the desired new position in the machine.

A toolstation is automatically defined when there is an overlap from punches with dies. This, meaning that a toolstation is considered a station when e.g. there is an exact position of punch and die opposite of each other. When there is a shifted position but still overlap in 

between punch and die, this is still considered a tool station. Even when two punches are opposite of a single die, which can be useful bending constrained bends, this is considered a toolstation. These stations can be repositioned without losing their relative positioning.

Station view is not changing anything to the tool details.

Bend Sequence

1. Introduction

DA-69T Operation Manual

When a tool configuration is available, the bend simulation can be started to determine a bend sequence for the active product. The bend sequence determination is started by tapping the navigation button Bend Sequence.

DA-69T Operation Manual


The bendsequence determination can be realised by automatic calculation starting with the bent product. It is also possible determining the sequence manually starting with the flat 

product, not using the automatic calculation.

In the bendsequence screen the product appears between the tools in a possible last bend position. When starting the simulation, the product is shown in its final state. In order to obtain a bend sequence, the product must be unfolded from the last bend to the first. This can be done with the available function keys.

When it is prefered to start with a unfolded product to manually chose the bendsequence, this can be chosen under the command button Bend Sequence.

(1)  View select

Within the bendsequence screen views can be switched upon required choice.

The view functions are located oposite of the command buttons in the main screen.

DA-69T Operation Manual

(2) Bend selector

Within the bendsequence screen bends can be selected and navigated thru with the bend selector. In the top of the screen the number of bends is indicated with preliminary bend selectors. After completing the bend sequence, these are all colored, active and show a turn indicator.

DA-69T Operation Manual

From then bends can be tapped to easily to select the desired bend data. In the bend selector the turn indicator will be displayed showing green, yellow or red colors to indicate the level of complying the assignments of the bend sequence.

DA-69T Operation Manual

2. Unbend product

In order to generate a CNC-program the bend sequence must be known. There are two ways to achieve this:

• Press the function key Compute. The control will automatically compute the quickest 

possible bend sequence for this product.

• Press the function key Unbend repeatedly, until the product is completely unbent.

When the product is completely unbent, press the function Bend sequence and Save to generate and save the CNC-program.

DA-69T Operation Manual

3. Manual selection of bends

Normally the control proposes the next (un)bend in a sequence. This is computed by the control depending on the programmed assignments and of course the product shape and applied tools. For various reasons it can be necessary to choose another bend for the bend sequence. The bend sequence can be changed/determined through the function Manual 

Selection. When the function Manual Selection has been choosen, a new window is opened.

DA-69T Operation Manual

4. Assignments

(1)  Introduction

The Assignments are parameters with which the bend sequence computation is controlled.

The assignments screen is opened from the tool configuration screen with the function key 

Assignm.

Automatic bend sequence computation works with several conditions in order to find an optimum between a minimum production time, handling possibilities without product/machine and product/tool collision.

In order to find one of the optimums you must program several computation parameters with which the bend sequence can be computed. Some of these parameters are machine-related and some are related to product accuracy, handling possibilities and turn times.

DA-69T Operation Manual

(2) Assignments - general

Optimisation degree

Range 1-5.

The number of alternatives to be computed for each bend must be entered here.

The higher this number the more alternatives are to be examined by the control, so the longer the computing time will be:

1 - lowest optimisation, fastest computation

2 - low optimisation, fast computation

3 - medium optimisation, medium computation

4 - high optimisation, slow computation

5 - highest optimisation, slowest computation

(3) Assignments - Backgauge possibilities

DA-69T Operation Manual

5. Show bend sequence

When the function Show Bend Sequence has been pressed, a graphical overview of the bend sequence is shown.

DA-69T Operation Manual


This option can be called at any time after the first unbend has been made. The graphical overview displays the determined bends as well as the not yet determined bends (question mark sign).

Each image in the overview can separately be enlarged or reduced with the available functions. The images can also be rotated by finger movement.

Profile-T

1. Introduction

(1) General

The Profile-T offline program offers a similar user interface as a DA-Touch line Delem control. The previous chapters, describing the operation and use of the DA-Touch control should be used as a reference for using this offline software. This chapter will focus on a few special functions that are only available in the Profile-T software.

(2)  System requirements

To run Profile-T on a computer it should at least be equipped with the following features:

• IBM-compatible PC;

• Minimum Screen resolution of 1024x768

• Windows XP / Windows 7;

• CD-ROM Player (only for CD-ROM distributed systems);

• Free USB port

(3) Profile-T distribution & manuals

Depending on the purchase package the Profile-T software is distributed on a CD-ROM or can be generated at the control.

2.  Profile-T operation

(1) Profile-T principle

The next figure shows the start page of Profile-T:

DA-69T Operation Manual

(2) Machine library

It is important that the parameters in Profile-T are the same as in the control on the machine. 

In this way the offline generated programs are 100% compatible with the control system. In Profile-T you install several machines in order to use 1 offline programming station for the complete machine range on the production floor.


(3)  Print functionality (Profile-T2D and Profile-T3D only)

In Products mode it is possible to generate a print out of the selected product (Profile-T 2D and Profile-T 3D only). When pressing the button 'print' the standard Windows printer menu is opened to select the desired printing device and printer settings


(4) Transfer mode

When the product design and CNC program generation are finished, this data can be transferred in Transfer mode to e.g. a USB memory device.
