HEIDENHAIN TNC 410 - Manual (Page 183)

8 Programming: Cycles 170
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 pocket floor
ú Plunging depth (incremental value):
Infeed per cut. The TNC will go to depth in one
movement if:
■ The plunging depth and the milling depth are equal
■ The plunging depth is greater than the milling depth
The milling depth does not have to be a multiple of
the plunging depth.
ú Feed rate for plunging: Traversing speed of the tool in
mm/min during penetration
ú Finishing allowance: Allowance in the machining
plane
ú Rough-out angle: Direction of the roughing-out
movement The rough-out angle is referenced to the
main axis of the machining plane. Enter the angle so
that the cuts can be as long as possible
ú Feed rate: Feed rate for milling in mm/min
