FLOOR FINISHING (Cycle 23)
The TNC automatically calculates the starting point for
finishing. The starting point depends on the available
space in the pocket.
The tool approaches the machining plane smoothly (in a vertically
tangential arc). The tool then clears the finishing allowance
remaining from rough-out.
ú
Feed rate for plunging: Traversing speed of the tool
during penetration
ú
Feed rate for milling Q12: Traversing speed for milling

;FEED RATE FOR MILLING
SIDE FINISHING (Cycle 24)
The subcontours are approached and departed on a tangential arc.
Each subcontour is finish-milled separately.
Before programming, note the following:
The sum of allowance for side (Q14) and the radius of the
finish mill must be smaller than the sum of allowance for
side (Q3, Cycle 20) and the radius of the rough mill.
This calculation also holds if you run Cycle 24 without
having roughed out with Cycle 22; in this case, enter “0”
for the radius of the rough mill.
The TNC automatically calculates the starting point for
finishing. The starting point depends on the available
space in the pocket.

Plunging depth Q10 (incremental value):
Dimension by which the tool plunges in each infeed
ú
Feed rate for plunging Q11: Traversing speed of the
tool during penetration
ú
Feed rate for milling Q12: Traversing speed for milling
ú
Finishing allowance for side Q14 (incremental value):
Enter the allowed material for several finish-milling
operations. If you enter Q14 = 0, the remaining
finishing allowance will be cleared.
