Defining behavior when positioning parallel axes with FUNCTION PARAXCOMP

Application

The FUNCTION PARAXCOMP function is used to define whether the control takes parallel axes into account in the traversing movements with the associated main axis.

Description of function

If the FUNCTION PARAXCOMP function is active, the control displays an icon in the Positions workspace. The icon for FUNCTION PARAXMODE may cover an active icon for FUNCTION PARAXCOMP.

Positions workspace

FUNCTION PARAXCOMP DISPLAY

Use the PARAXCOMP DISPLAY function to activate the display function for parallel axis movements. The control includes movements of the parallel axis in the position display of the associated main axis (sum display). Therefore, the position display of the main axis always displays the relative distance from the tool to the workpiece, regardless of whether you move the main axis or the parallel axis.

FUNCTION PARAXCOMP MOVE

The control uses the PARAXCOMP MOVE function to compensate for movements of a parallel axis by performing compensation movements in the associated principal axis.

For example, if a parallel-axis movement is performed in the negative W-axis direction, the principal axis Z is moved simultaneously in the positive direction by the same value. The relative distance from the tool to the workpiece remains the same. Application in gantry-type milling machines: Retract the spindle sleeve to move the cross beam down simultaneously.

FUNCTION PARAXCOMP OFF

Use the PARAXCOMP OFF function to switch off the PARAXCOMP DISPLAY and PARAXCOMP MOVE parallel axis functions.

  • The following actions cause the control to reset the PARAXCOMP parallel-axis function:
  • Selection of NC program
  • PARAXCOMP OFF

When FUNCTION PARAXCOMP is not active, the control does not display the corresponding icon and the additional information after the axis designations.

Input

NC programs contained in this User's Manual are suggestions for solutions. The NC programs or individual NC blocks must be adapted before being used on a machine.

  • Change the following contents as needed:
  • Tools
  • Cutting parameters
  • Feed rates
  • Clearance height or safe position
  • Machine-specific positions, e.g. with M91
  • Paths of program calls

Some NC programs depend on the machine kinematics. Adapt these NC programs to your machine kinematics before the first test run.

In addition, test the NC programs using the simulation before the actual program run.

 
Tip

With a program test you determine whether the NC program can be used with the available software options, the active machine kinematics and the current machine configuration.
