Compensation for real workpiece surface
If the actual workpiece surface deviates from the assumed, theoretically ideal surface position, it is compensated for by distance control.
Compensation of the deviation can basically take place in two modes:
- in the tool direction
- orthogonal to the surface
Compensation in tool direction
In this mode, the cutting curve orientation is maintained despite the height offset. This is essential for a (pipe) feedthrough, for example.
Compensation orthogonal to the surface
In this mode, the projection (top view) of the machining operation remains identical, i.e. the shape is not distorted but only offset in height. Projection in X/Y remains stationary despite compensation.
