FLOOR FINISHING (Cycle 23)
The tool approaches the machining plane smoothly (on a vertically
tangential arc) if there is sufficient room. If there is not enough room,
the TNC moves the tool to depth vertically. The tool then clears the
finishing allowance remaining from rough-out.
 Feed rate for plunging Q11: Traversing speed of the
tool during penetration.
 Feed rate for milling Q12: Traversing speed for
milling.
 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. Input range: 0 to 99999.9999

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