Cycle parameters

Finished part diameter

Q223: Diameter of the

completely machined stud. Input range 0 to
99999.9999

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

Finishing allowance for side

Q368 (incremental):

Finishing allowance in the working plane. Input range
0 to 99999.9999

Feed rate for milling

Q207: Traversing speed of the

tool in mm/min while milling. Input range 0 to
99999.999; alternatively FAUTO, FU, FZ

Climb or up-cut

Q351: Type of milling operation with

M3:
+1 = climb milling
–1 = up-cut milling
