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.
