8 Set-up clearance 1 (incremental value): Distance
between tool tip (at starting position) and workpiece
surface.
8 Depth 2 (incremental value): Distance between
workpiece surface and bottom of pocket
8 Plunging depth 3 (incremental value): Infeed per cut
The TNC will go to depth in one movement if:
„ the plunging depth is equal to the depth
„ the plunging depth is greater than the depth
8 Feed rate for plunging: Traversing speed of the tool
during penetration
8 First side length 4 (incremental value): Pocket
length, parallel to the reference axis of the working
plane
8 Second side length 5 : Pocket width
8 Feed rate F: Traversing speed of the tool in the
working plane
8 Clockwise
DR +: Climb milling with M3
DR –: Up-cut milling with M3
8 Rounding radius: Radius for the pocket corners.
If radius = 0 is entered, the pocket corners will be
rounded with the radius of the cutter.
Calculations:
Stepover factor k = K x R
K: Overlap factor, preset in the PocketOverlap machine parameter
R: Cutter radius
