ú Setup clearance (incremental value): Distance
between tool tip (at starting position) and workpiece
surface
ú Milling depth (incremental value): Distance between
workpiece surface and bottom of pocket
ú Plunging depth (incremental value):
Infeed per cut. The tool will advance to the depth in
one movement if:
■ the plunging depth equals the depth
■ the plunging depth is greater than the depth
ú Feed rate for plunging: Traversing speed of the tool
during penetration
ú CIRCLE RADIUS: Radius of the circular pocket
ú Feed rate F: Traversing speed of the tool in the
working plane
ú Direction of the milling path
DR + : climb milling with M3
DR – : up-cut milling with M3
