FLOOR FINISHING (Cycle G123)
The tool approaches the machining plane smoothly (in a vertically
tangential arc). The tool then clears the finishing allowance remaining
from rough-out.
8 Feed rate for plunging Q11: Traversing speed of the
tool during penetration.
8 Feed rate for milling Q12: Traversing speed for
milling.
8 Retraction feed rate Q208: Traversing speed of the
tool in mm/min when retracting after machining. If
you enter Q208 = 0, the TNC retracts the tool at the
feed rate in Q12.

The TNC automatically calculates the starting point for
finishing. The starting point depends on the available
space in the pocket.
