Fundamentals
In addition to the main axes X, Y, and Z, the parallel axes U, V, and W, are available. A parallel axis is, for example, a spindle sleeve for boring so that smaller masses are moved on large machines.
The control provides the following functions for machining with the parallel axes U, V and W:
- FUNCTION PARAXCOMP: Define behavior when positioning parallel axes
Defining behavior when positioning parallel axes with FUNCTION PARAXCOMP
- FUNCTION PARAXMODE: Select three linear axes for machining
Select three linear axes for machining with FUNCTION PARAXMODE
If the machine manufacturer has already enabled the parallel axis in the configuration, the control takes this axis into account in the calculations, without you having to program PARAXCOMP. Since the control then continuously offsets the parallel axis, you can for example probe a workpiece even with any position of the W axis.
In this case, the control displays a symbol in the Positions workspace.
Please note that PARAXCOMP OFF does not deactivate the parallel axis in this case, but the control reactivates the standard configuration. The control deactivates automatic calculation only if you include the axis in the NC block (e.g., PARAXCOMP OFF W).
After the control has booted, the configuration defined by the machine manufacturer is in effect.
