Plunge Motions
Plunge motions make the tool plunge before a selected Automatic Cut motion (or another approach motion).
The tool will perform the following motions:
Move at RAPID speed along the retract surface to the location directly above the start point of the next Tool Motion. This location is determined as follows:
In case of a retract plane, the projection of the start point of the next Tool Motion on the retract plane.
In case of a retract surface of revolution, the intersection of the tool axis at the start point of the next Tool Motion with the retract surface.
Plunge at RAPID speed to the location offset from the start point of the next Tool Motion by (CLEAR_DIST + a), where a is an extra offset value, which depends on the type of NC sequence. It is:
STEP_DEPTH—For Volume, Local, Face, Profile, Pocket, and Trajectory milling.
ROUGH_STEP_DEPTH—For Conventional milling.
OFFSET_INCREMENT—For Surface-by-Surface Contour milling and Cutline machining.
0—For all other types of NC sequences.
Move at PLUNGE_FEED to the start point of the next Tool Motion.
