Getting started with VisiTouch 19

Depending on software evolutions and the press brake controlled by the VisiTouch (configuration/capabilities), the present manual may not fully correspond to  the VisiTouch that you currently have. However, differences are only minor.

This manual describes all features of VisiTouch 19 software version VisiTouch19_Press_PS_PC_V1.0.9 and above.
Touchscreens are pressure sensitive.
Do not press down hard on the screen.
Pressing hard on the screen will damage the display. Such damage is not covered by manufacturer warranty!

Do not use sharp and/or pointed objects (sheet metal, screwdriver, metal pen ball, etc.) to touch the screen; only use your fingers (with or without gloves on) or a plastic pen. 

Make sure that your gloves do not have metal particles encrusted in the finger tips as they may also damage the screen.

Take a few minutes to practice pressing gently on the screen, you will find that the screen is very reactive and it is pleasant to use.

This parameter allows choosing between kg/mm2, N/mm2 and psi(*1000) for the sigma unit to be used in the VisiTouch.

Show axes

position values

This function will display the axes positions on the Bend Numerical Page (see page 16).

  • When set to no, the position of axes Y1, X and R is displayed during the beam’s movements.
  • When set to yes1, the positions of the axes (Y1, Y2, X and R) are displayed during their respective movements.
  • When set to yes2, the positions of the axes (Y1, Y2, X and R) are constantly displayed under their respective set-point values.

Show bent part

This parameter, when activated, lets the operator see the state of the part before and after the bend in the Bend Sequencing page.

Materials

Touching Materials opens the Materials page, where the default characteristics for each material can be changed, or a new material can be configured.
To be allowed to access the Materials page, a level 2 password is required.

The Materials page displays:

  • Material: Selected material (here Steel).
  • Default thickness for the material.
  • Default sigma: Default sigma for the material (here 45).
  • Displayed: If the material will be available to be selected for use (here yes).
  • Predefined thickn.: Allows defining up to 7 different predefined thicknesses for the selected material.
  • Thickness min/max: Determines the maximum and minimum accepted thickness for the selected material.

Three predefined default materials are available (steel, stainless steel, aluminum), but

others can be added.

To add a material:
1. Touch Material and select a non-configured material (Mater X) from the list.
2. Enter the new material’s characteristics.
3. Touch the name (Mater X) to display the keyboard and enter the name of the new material.

BDC correction

This parameter allows the operator to apply a permanent correction to the Bottom Dead Center position.
Please note that this correction is always applied and is NOT shown in the correction page. If you experience big differences from what you expect to get, maybe check the value of this parameter.

Menu horizontal

alignment

This parameter allows the operator to choose on which side – Left of Right – he prefers to have the side bar containing the Menu Button .

Menu vertical

alignment

This parameter allows the operator to choose if he prefers to have the menu displayed at the Bottom or at the Top of the screen when he presses the Menu Button .

Clear indexation

When activated, this function clears the index and the machine will search for them, as it does when turning the power on, allowing the operator to re-index its machine without turning it off.

USB Explorer

When this parameter is set to yes, it is possible to browse the USB key from the USB transfer screen (see USB Transfer, page 15).
A USB key must be inserted.
Preferably use a specific USB key for transfering parts and VisiTouch Data instead to use a generic memory stick full of data programs that are not relevant for the numerical control.

Beam trace

When this parameter is set to yes, this small button is displayed on the Status page (see page 7).
By activating/deactivating it, one can start and stop the recording of beam traces.

Auto open beam

traces

When activated, this function will open the beam trace screen automatically at the end of the recording.

Default retraction

This parameter allows defining the default value displayed in the Extra bending parameters (see page 19) when activating the back gauge retraction function.
In TouchProfile Mode (see page 29), when a retraction is necessary, the numerical control will automatically calculate and activate the function. The calculated value can naturally be manually modified.

Set Clock

Allows the user to set the time and date on the VisiTouch.

Touchscreen

Calibration

This function allows the calibration of the touch screen
Setting Instructions:
Simply follow the instructions on the page to calibrate the touchscreen.
Use your finger or the plastic tip of a pen to calibrate the Touchscreen. Never use sharp objects as this will damage the screen.

Offset Pinch

Point function

When this parameter is set to yes, the Offset Pinch Point (see page 22) function is available in the Extra Bending Parameters.

Show button up

When this parameter is set to yes, the button up is available when the beam is not at TDC.

Upward command

Go to TDC max

Go to next TDC

The beam goes up as long as the button is pressed.

The beam goes to TDC max

The beam goes to the next TDC. 

(first to programed TDC, then to the TDC max)

Show L first

This function allows choosing the data entry mode for the back gauge on the Bend Numerical Page or EasyBend Page. When set to yes, the length of the flange icon is displayed by default. When set to no, the icon for the position in mm of the back gauge is displayed.
When set to never, the position of the back gauge is no longer linked to the bending angle, i.e. the position is never recalculated when the bending angle is modified.
The default value for this preference is never. Note that completely formatting the machine will reset this preference to its default value.
The mode is not available for graphical parts (see also Set-point back gauge (X axis) / flange length, page 17).

Beam stops

during retraction

When this parameter is set to yes, the down movement of the beam is stopped and the beam is maintained in closed loop at pinch point during the retraction. The beam cycle will resume as soon as the back gauge has finished its retraction.
Manual Axes Movement

In the course of setting up a machine, it is sometimes necessary to be able to move the axes manually, for example when changing the tooling. This can be done on this page.

(Menu Button) → Manual movement
Setting Instructions:
1. Select the axis that you want to move:
• by selecting the desired axis from the drop down menu.
• by touching this icon for the crowning axis.
• or for the tool clamping devices (if available).
2. Touch the buttons to move the selected axis.
In the course of setting up a machine, it is sometimes necessary to be able to move the axes manually, for example when changing the tooling. This can be done on this page.
By selecting a line where the padlock is open , it is possible to move (Low Speed Down movement) Y1 or Y2 only. This is an easy way to return an unsynchronized beam back to parallel to the table.
3. Use the foot switch (Low Speed Down movement) and this button (High Speed Up) to move the beam.

Desynchronized

Beam

By selecting a line where the padlock is open , it is possible to move (Low Speed Down movement) Y1 or Y2 only. This is an easy way to return an unsynchronized beam back to parallel to the table.

Linked axes

Depending on the configuration of the machine, a padlock can be displayed next to the axes selected. This means that the movements of these axes are interlocked. In a similar fashion as here above, when the padlock is open , it is possible to select and move a single axis.
Information page

The Information page displays the names and versions of the softwares installed on the VisiTouch.

(Menu Button) → ... → Service → Information
USB Transfer
(Menu Button) → Other menus → USB transfer

This function opens the USB transfer screen, which allows the operator to transfer data between the VisiTouch and a USB key.

Copying parameters from USB to NC requests a level 3 password or, for endusers, the restore password.

Precautions

For a smooth transfer, please take the following precautions into consideration:
• The USB port of the VisiTouch is meant to be used only with a storage media of the "Memory stick" type.
• The port is a standard USB 2.0 port, USB 1.1 compatible.
• USB 3.0 key that are USB 2.0 compatible, should normally work. There’s however no guarantee, as it depends of the firmware of these new keys.
• CD and external HDD are not accepted.
• Although unlikely, it is possible to find a USB key that is not compatible with the VisiTouch. If so, try with another one.
3 rules for a fast and easy transfer:
→ Use a USB key dedicated to files transfer with the VisiTouch.
→ Less files means a faster transfer.
→ The file’s path on the key is limited to 255 characters.

Importing parts

from PC program

PC VisiTouch is the offline software which has the same features as the controller. It is possible to transfer parts or tools from one to another.
PC VisiTouch is available as an option, please contact the machine manufacturer if you would like to purchase it.

Basic Page Description

 
Bend Numerical Page

Available

functions on the

Bend Num page

The Bend Numerical Page is normally the working page, from which the bends are executed, and most of the navigation originates from and leads to.

Program  Name

Touching the program name allows creating a new one, saving it and more. See Managing Programs, page 37 for more information.

Current step (sequence) number

Touching the step number will open a yellow pop-up window as shown here, with 3 different actions to choose from:
• Insert step: this function will insert a step after the current one.
• Delete step: this function will erase the current step.
• Go to step: this function allows jumping directly to the desired step.
The Insert step and Delete step functions cannot be used on parts created with the TouchProfile Mode (see page 29).

Set-point beam (Y axis) / bend angle




The VisiTouch has three different modes to manage the Y axis. Touching one of the icons on the left allows going from one mode to another. The three modes are:
in this mode, the operator simply enters the desired angle and the VisiTouch will calculate the position at which the beam will stop (BDC).
in this mode, the operator can see the calculated target of the angle. It is possible to change the value.
this is the bottoming mode. When the beam stops, or when the target value is reached, the bending cycle continues (dwell time, return). When activated, the calculated bottoming value is displayed in gray. It is however possible to modify this value, which will then be displayed in black. It can only be used if both the tools accept bottoming (see Punches, page 24 and Dies, page 26).

Set-point back gauge (X axis) / flange length




The VisiTouch has three different modes to manage the back gauge X axis. Touching the icon at the top of the screen allows going from one mode to another. The modes are:
when activated, the operator simply enters the desired length for the flange and the VisiTouch will calculate the position for the back gauge X axis. This mode is only available when programming a part with the Numerical Mode (see page 32).
when deactivated, the operator enters the targeted position for the back gauge X axis.
this is the relative mode. The back gauge makes a relative movement of the value entered. When the value entered is negative, the back gauge moves in the operator’s direction.
The relative mode is activated/deactivated by pressing the back gauge icon for 2 seconds.
Relative movement is not possible on the first sequence (neither on Easy Bend) or on graphical parts.
User Preference Show L first (see page 12) allows choosing which mode is displayed by default first.

Back gauge finger type

The back gauge dimensions are defined in the machine parameters. This function allows browsing through the available support and stop positions of the back gauge. This function may be available, or not, according to the machine configuration.

Optional axes

All the various optional axes of the machine are displayed in this zone. Their respective values are calculated by the VisiTouch and are displayed in gray. They can however be manually modified, but are then displayed in black.
To restore the calculated value, simply press reset .

Quick access tab

Contains various settings for the current bend such as axes positions and bending parameters. If the machine has multiple axes, it’s possible to slide on the display in order to show the other axes.

User buttons tab

Contains various buttons depending on the configuration for machine functions such as tool clamping, pump activation or upward command.
The user buttons tab will only appear if configured by the machine manufacturer.

Extra bending

parameters

Extra bending parameters can be found on this page, which displays parameters related to the part, and depending on the VisiTouch configuration and the type of action performed, also displays various settings for the current bend. Most of these parameters can also be found in the Quick access tab.

Material

This is not a sequence parameter, but of course a part parameter. Each touch on the material’s name selects the next available from the list of Materials (see page 9).

Material thickness

The default thickness, defined in Materials (see page 9), is automatically displayed when changing material. It is however possible to change it simply by touching this icon.
If on the other hand, the parameter Predefined thickn. (see page 9) is set to yes, a touch on this icon will open a numerical pad as show to the right, where the operator will be able to select directly one of the predefined thicknesses.
This is a part parameter

Material sigma

The default sigma, defined in Materials (see page 9), is automatically displayed when changing material. It is however possible to change it simply by touching this icon. This is also of course a part parameter.

Back gauge retraction

The back gauge retraction can be activated/deactivated at its Default retraction (see page 11) value using this icon. It is possible to modify the value by touching it. This is a sequence parameter, meaning it can be modified with each step of the program.

Speed change threshold and bending speed

The distance parameter allows the operator to increase the height of the speed change point. The speed parameter allows decreasing the bending speed from its maximum value defined in the machine parameters.

Bending length / Position offset

This parameter defines the width of the sheet metal part that will be pinched between the tools. It is used to calculate the bending force.
If this parameter is not activated (gray), the VisiTouch will not calculate the bending Force and the Crowning.
The second value defines the position of the sheet metal in the machine.

Step bending

When a large radius bend has been programmed (see L-Alpha Mode, page 33), its parameters are displayed here. It is possible to modify them directly here.
Programming 99 x will automatically calculate the maximum possible step bends. The resulting value may be reduced. However, if it is increased over the maximum calculated value, the resulting radius and angle will be drastically affected.
The large radius bending function is deactivated when this field is grayed.

Slow speed return

This parameter allows slowing down the speed of the beam after the bend, and is generally used when the part has a long flange and the operator tries not to let it “fall down too fast”.
The beam will return at low speed up while the operator holds the foot pedal. It switches to high speed up when either the pedal is released or Pinch Point is reached, whichever comes first.
When this field is deactivated (grayed), the beam moves back up directly at HSU (High Speed Up).

Dwell time

Allows defining the duration of the dwell time, meaning the time during which the punch remains at BDC before coming back up.
When the icon is crossed , it means that there is no automatic return of the beam after TDC. This is a sequence parameter, meaning it can be modified with each step of the program.
When this field is deactivated (grayed), the default Dwell Time value defined in the machine parameters is applied.

Force

The force is automatically calculated by the VisiTouch, according to the Material, the Material thickness, the Material sigma and the Bending length / Position offset. The value can also be manually modified here.

Opening (TDC)

For parts created with a profile (see TouchProfile Mode or L-Alpha Mode), this value is automatically calculated to allow the operator enough room to extract its bent part from between the tools. It is however possible to change it manually.
For part created manually (see Numerical Mode), this parameter uses the default minimum value defined in the machine parameters. It can however be programmed here.
Creating a “New part” reinitializes it to its default value.
When this field is deactivated (grayed), the beam moves back all the way up to its maximum limit switch.

Crowning

The crowning function is activated here. It is automatically calculated, according to the Material, the Material thickness, the Material sigma and the Bending length / Position offset. If the crowning needs correction, use the Crowning (see page 35) function in the correction page.
The value can be manually changed by operator. It will however be automatically recalculated if any of the values used for its calculation is changed.
When the crowning function is deactivated (gray icon), the crowning system physically remains to its last position and does not automatically return to 0.0 mm. Keep that in mind when using this function – or not – between one sequence and the following.

Number of parts

The operator can enter here the total amount of parts to be produced. Every time all the sequences of the program are executed, hence a part is completed, this counter is updated of one unit (increased or decreased, see Program counter mode, page 14). When the amount of parts is reached, a yellow pop-up window signals it to the operator.

Back gauge manual control

Activating this parameter gives manual control over the back gauge movement. This means the operator must personally give the start to the back gauge movement, using for example the foot switch or the start button.

Offset Pinch Point

This function allows making a bending cycle further away from the matrix, for example to close the opened side of a box, as shown on the right.
Once activated, this function forces the VisiTouch into bottoming mode (see Set-point beam (Y axis) / bend angle, page 17).
With this function, the Speed Change Point occurs higher, and the operator can inch the beam down with short impulses on the pedal, until the proper height is reached. The parameters Speed change threshold and bending speed (see page 20) can also be useful in this situation.

Proceeding this way is normally used for unit or small series. If however the number of parts is large, the operator can enter a target value in the bottoming field, which will then turn black. This way, the VisiTouch will execute a normal bending cycle, stopping the beam at the programmed value, i.e. saving a lot of production time.

Hemming

Allows making conventional die hemming bends. (optional)
Copy to All Function
This function allows copying a defined value to all the steps of the current program. It appears in the numerical pad of relevant fields, such as Bending length / Position offset, Force, Bending and Corrections, etc.
It is also possible to use the Copy to All function with fields that do not require a numerical pad by simply holding the button for 2 seconds. The pop-up Spread status ? will then appear.

Tools Management

Tools management allows the creation and configuration on the VisiTouch of the tools to be used on the machine. These tools are then taken into account in bend calculations.
Once a punch and die are created and selected, you can select the bend angle you require as well as the flange length (L). The VisiTouch then calculates the positions for axes X and Y for the bend.

Naming Tools
It is recommended that you use naming conventions for your tools.
Below you will find a simple convention allowing you to precisely identify a punch or die through its name.
Of course, depending on your needs you may need to create more rules for punch and die naming.

Punches

The name of the punch should be built in the following manner: first its angle, followed by its type, and then whether it is inverted or not.
Following these rules, here are some examples of punch names: 90_N_i, 60_G, 30_S, and so on, and so forth.

Dies

The name of the die should be built in pretty much the same manner: first its width (Ve dimension), followed by its angle, and then whether it is inverted or not.

Following these rules, here are some examples of die names: 12_86_i, 16_86, 20_30, and so on, and so forth.

Creating a Part Program

There are three ways to create a program part: with the TouchProfile Mode, with the Numerical Mode (see page 32), and with the L-Alpha Mode (see page 33).
In this chapter the machine is considered operational: machine parameters, tools (see Tools Management, page 24), materials (see Materials, page 9), etc. are already configured and programmed.
TouchProfile Mode
Bend Numerical Page →
In this mode, the operator can very intuitively draw a profile directly on the screen.
Settings Instruction:
1. Touch the program number, select New program in the list, and touch Graphical 2D.
2. First select the material, the Material thickness (see page 19) and the tools to be used for the part by touching their respective icons.
3. Draw the profile by touching the screen where you want to add a segment.
Touching this icon allows erasing the last segment added.
4. Touch on the middle of a segment to modify its value.
5. Touch on an angle to modify its value. Touching the icon will open a yellow pop-up, in which it possible to:
• Activate (and deactivate) a special tool by touching its icon, and select it from a list by pressing ???.
• Change the value of the radius (see also Step bending, page 20) and define how many steps the NC will make to execute it.
6. Should it prove difficult to select a particular segment or angle, it is possible to zoom on an area by touching this button and then on the desired zone.
One can also choose to enter the length and angle values in the L-Alpha Mode page by pressing this button.
7. Once all the segments and angles are adjusted, press this button to access Bend Sequencing.
Bend Sequencing
Bend Numerical Page →
Once the shape of the part has been defined, the bending sequence for the part can be determined.
Setting Instructions:
1. Touch the bend sequence calculation button . Once the sequence is calculated, the Bend 2D screen is displayed.
Pressing the back button will erase the last bend in the sequence. If you wish to delete all bends, simply touch the button.
2. Immediately after determining the last bend to be selected, the Bend 2D screen here below is displayed.
3. In the Bend 2D page, the operator must determine the back gauge and part position for each bend, and if necessary Extra Bending Parameters (see page 19).
4. Press and select Bend numerical to return to the Bend Numerical Page.
5. Start the hydraulic pump motor (by pressing this button if available. It turns red when the motor is running).
6. Press the button to position the machine according to the data that were just entered.
7. When the machine is ready to bend, a button is displayed.
8. If you want to repeat the same step in order to apply all the necessary corrections to it, switch to the Semi-Automatic mode (see page 34).
9. Press the foot switch to execute the bend.
Numerical Mode
It is also possible to simply create a part program directly on the Bend Numerical Page.
Setting Instructions:
1. Touch the program number, select New program in the list, and touch Numerical.
2. First select the tools to be used for the part by touching their respective icons (see Tools Management, page 24).
3. Touch the Material’s name (here Steel) until the one used is displayed.
4. Touch the Material thickness, and select or enter the proper one.
5. While in the Extra Bending Parameters’ section, enter the Bending length / Position offset, and other sequence parameters (Opening (TDC), Slow speed return, etc.).
6. Touch the numerical value next to the angle icon , and enter the value for the first bend you wish to create (here 90°).
7. Touch the numerical value next to the segment length icon , and enter the value for the first segment you wish to create (here 30.00 mm).
8. Add the next bend to the program by touching .
9. Proceed in the same manner to create the other segments of the part.
10. Touch to return to the first bend.
11. Start the hydraulic pump motor (by pressing this button if available. It turns red when the motor is running).
12. Press the button to position the machine according to the data that were just entered.
13. When the machine is ready to bend, a button is displayed.
14. If you want to repeat the same step in order to apply all the necessary corrections to it, switch to the Semi-Automatic mode (see page 34).
15. Press the foot switch to execute the bend.
L-Alpha Mode
Bend Numerical Page →
In this mode, the operator can define each step (length or angle) of a profile on a table.
Setting Instructions:
1. Touch the program number, select New program in the list, and touch Graphical 2D.
2. Press this button to access the L-alpha mode.
3. First select the material, its thickness and the tools to be used for the part by touching their respective icons.
4. Touch the first value in the table (here 200.00). The window to the right is displayed.
5. Enter the value for the first segment’s length and touch the button to add another step.
Click on OK when prompted to create new step.
6. Proceed in the same manner for all steps and angles of the profile.
7. If a bend needs special parameters (large radius, special tool), press in the more field of the corresponding sequence.
A special punch or /and die means there must be an additional working station.
8. A yellow pop-up is displayed, in which it possible to:
• Activate (and deactivate) a special tool by touching its icon, and select it from a list by pressing ???.
• Change the value of the radius (see also Step bending, page 20) and define how many steps the NC will make to execute it.
9. A small More icon shows that something special is programmed on the bend.
10. To remove the icon (and special parameters), return to the yellow popup, touch all the activated functions to make them turn gray, and select OK.
11. Once all the segments and angles are adjusted, press this button to access Bend Sequencing (see page 30)
Bending and Corrections
All program corrections are made in the Bend Numerical Page (see page 16). According to his preferences, the operator can choose to execute all the steps of the program one after the other, making corrections along the way. Or he can choose to apply all the corrections necessary to the same step before moving to the next one using the SemiAutomatic mode.
Corrections can be made to:
• The angle (Y1 + Y2, see Angle Correction (Y axis), page 35 and/or crowning if available, see Crowning, page 35),
• The back gauge position (X and R, if available), see Back gauge Correction, page 36.

Semi-Automatic

mode

The semi-automatic mode allows repeating the same sequence indefinitely. It is used when the operator wants to apply corrections to his part one bend after another. He can thus execute the same step until he gets the desired result, before moving to the next one by means of the button. The semi-automatic mode is activated (and deactivated) by touching for more than one second on the button

Angle Correction

(Y axis)

After physically measuring the angle, if corrections are to be made, they must be done on this page, and not directly in the program step.
Bend Numerical Page →
Setting Instructions:
1. Touch the angle correction icon, and enter the physically measured value of the angle. The numerical control will automatically calculate the Y1 and Y2 axes corrections.
Pressing this button will reset all angle corrections.
2. Depending on the position of the sheet metal in the press, it may be necessary to fine-tune the beam’s corrections. It is possible by simply touching this icon or this one, and entering the desired values.

Crowning

3. Corrections to the crowning value can be made by touching this icon .
4. The numerical control automatically calculates the Pinch Point height. If it needs correction, it can be done by touching this icon
The grayed value next to the Pinch Point correction icon is the value calculated by the numerical control, and thus the value onto which the correction will be applied.

Back gauge

Correction

5. Touching the values next to any axes allows entering a correction
The axes corrections can be positive or negative and will be added to the axes positions.
The back gauge positions corrections can also directly be made on the Bend Numerical Page (see page 16).

Managing Programs

Because the production of parts follows cycles, the programs related to those parts need to be managed. They need to be stored, called into function, and so on.
On the VisiTouch, the Program name (see page 16) is displayed on the top left corner of different pages. Touching it will open the following menu:
Saving a Program
After creating a program, an operator can save it for later use:
1. Touch the Program name.
2. Touch Save part as... to save a new part. Give it a distinctive name using the alphanumerical keyboard, and validate with .
3. Or touch Save part to save the modifications made to an existing part.
4. The program is now saved in the VisiTouch.
Creating a Program
To create a new program:
1. Touch the Program name.
2. Touch New part.
3. A yellow pop-up windows asks what kind of program:
