Cycle parameters
U Feed rate for plunging Q11: Traversing speed of the
tool during plunging. Input range 0 to 99999.9999;
alternatively FAUTO, FU, FZ
U Feed rate for roughing Q12: Milling feed rate. Input
range 0 to 99999.9999; alternatively FAUTO, FU, FZ
U 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,
alternatively FMAX, FAUTO
