Cycle parameters
U Finished part diameter Q223: Diameter of the
completely machined stud. Input range 0 to
99999.9999
U Workpiece blank diameter Q222: Diameter of the
workpiece blank. Enter the workpiece blank diameter
greater than the finished diameter. The TNC performs
multiple stepovers if the difference between the
workpiece blank diameter and finished diameter is
greater than the permitted stepover (tool radius
multiplied by path overlap Q370). The TNC always
calculates a constant stepover. Input range 0 to
99999.9999
U Finishing allowance for side Q368 (incremental):
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
