Hydraulic press brake CybTouch 8 controller Manual

CybTouch 8 controller

Getting started with CybTouch 8

Depending on software evolutions and the press brake controlled by the CybTouch 8 controller (configuration / capabilities), the present manual may not fully correspond to the CybTouch that you currently have. However, differences are only minor.

CybTouch 8 controller

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.

Set Axis

Allows the operator to manually adjust the position of the back gauge (axes X and R) and the beam (axes Y1 and Y2).

CybTouch 8 controller


The Maintenance page displays the hardware status of the CybTouch and lets the operator perform different maintenance actions.

Internal backup

This function is specially designed for OEM and support. Usually a machine parameters’ backup is made by the machine manufacturer or the company who services the machine. This backup allows a maintenance technician to restore original working parameters if necessary.

Should there be a need to restore parameters, call on a maintenance technician and follow his instructions.

Do not try to use this function unless you are in dire need.

Basic Page Description

Bend Numerical Page

CybTouch 8 controller

CybTouch 8 controller

Bending length

This parameter defines the width of the sheet metal part that will be pinched between the tools. It is used to calculate the bending pressure.

Step bending

When a large radius bend has been programmed (see L-Alpha Mode, page 27), 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.

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.

Dwell time

Allows defining the duration of the dwell time, meaning the time during which the punch remains at BDC before coming back up.

Opening (TDC)

For parts created with a profile (see TouchProfile Mode (optional) 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.


The crowning function is activated here. It is automatically calculated, according to the Material, the Material thickness, the Material sigma and the Bending length. If the crowning needs correction, use the Crowning (see page 29) 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.

Tools Management

Tools management allows the creation and configuration on the CybTouch 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 CybTouch then calculates the positions for axes X and Y for the bend.

How to create or modify a punch?

If no punch is yet created, the punch will have no name (??? is displayed). If a punch already exists, then the last punch used will be selected, here 60_N (modifications will not alter the existing punch as they will be saved under another name).

CybTouch 8 controller

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


How to create or modify a die?

If no die is yet created, the die will have no name (??? is displayed). If a die already exists, then the last one used will be selected, here 30_12 (modifications will not alter the existing die as they will be saved under another name).


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.


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

TouchProfile Mode (optional)

7. 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.
  • Define how many steps the NC will make to execute the step bending.

8. A small More icon shows that something special is programmed on the bend.

9. 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.

10. Once all the segments and angles are adjusted, press this button to access the Manual Bend Sequencing (see page 24).

Angle Correction(Y axis)

Bend Numerical Page →

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.


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.

Back gauge (X & R axes)


5. Touching this icon allows applying a correction to the back gauge X axis position.

6. Touching this icon allows applying a correction to the back gauge R axis position.

The back gauge positions corrections can also directly be made on the Bend Numerical Page (see page 14).

Saving and Loading a Program

Saving a Program

After creating a program, an operator can save the program in order to use it again:

  1. In the Bend Numerical Page, touch the Program number (e.g. P0).
  2. Touch Save program.
  3. Enter the number you wish to give to the program (e.g. 1 for P1), followed by “correct” button.
  4. The program is now called P1 and is saved in the CybTouch.

Error and Warning Messages

Following is a list of warning and error messages which may be displayed on the interactive message line of the CybTouch.There are two types of messages:
  • Warning Messages, which are displayed on a green background. They are information or instructions that will disappear automatically.
  • Error Messages (machine or NC errors), which are displayed on a red background.
They inform the user of an error occurring on the machine or NC, and sometimes require intervention by the end user or a technician.
