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:
n the plunging depth equals the depth
n the plunging depth is greater than the depth

ú

Feed rate for plunging: Traversing speed of the tool
during penetration

Feed rate F: Traversing speed of the tool in the
working plane
