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.

• Safety RS: Security distance between the tool and the back gauge for R axis.

• Retr. zone: Retraction zone.

8. Return to previous page .

To be allowed to save a tool, a level 2 password is required.

9. Touch the die name (here 30_12).

10. Touch Save tool to overwrite the existing tool or Save tool as if you want to save
your tool under another name.

11. Enter the name of the new die using the alphanumerical keypad.

We recommend that you follow the naming conventions explained in Naming
Tools (see page 28).

12. Touching the button brings you back to the program page, with the die you just
saved being selected and ready to be used.

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
