U U U U Set-up clearance 1 (incremental value): Distance
between tool tip (at starting position) and workpiece
surface
U U U U Milling depth 2 (incremental value): Distance
between workpiece surface and bottom of pocket
U U U U Plunging depth 3 (incremental value): Infeed per cut.
The tool will drill to the depth in one operation if:
n the plunging depth is equal to the depth
n the plunging depth is greater than the depth
U U U U Feed rate for plunging : Traversing speed during
penetration
U U U U 1st side length 4 : Slot length; specify the sign to
determine the first milling direction
U U U U 2nd side length 5 : Slot width
U U U U Feed rate F : Traversing speed of the tool in the
working plane
