Finishing allowance in the working plane. Input range
0 to 99999.9999
U Feed rate for milling Q207: Traversing speed of the
tool during milling in mm/min. Input range: 0 to
99999.999; alternatively FAUTO, FU, FZ
U Climb or up-cut Q351: Type of milling operation with
M3:
+1 = climb milling
–1 = up-cut milling
U Depth Q201 (incremental): Distance between
workpiece surface and bottom of pocket. Input range
–99999.9999 to 99999.9999
U Plunging depth Q202 (incremental): Infeed per cut.
Enter a value greater than 0. Input range 0 to
99999.9999
