Setting range 0 to 65535
During a finishing process based on the standard pattern (#0) of the
threading unit,
TC78 cutting (final cutting diameter in threading unit) is
repeated the number of times that has been specified in
TC83.
TC83 = 0 or 1:
Cutting based on the setting of
TC78 occurs once.
TC83 ≥ 2:
Finish-cutting is repeated the number of times specified in
TC83, and with
the depth-of-cut setting of
TC78/TC83.
<Supplementary description>
- Parameter
TC83 is valid only for #0, [#0]: it does not function for #1, [#1]
or #2, [#2].
- If
TC78 = 0, TC83 is valid.
For thread refinishing, one cutting operation is performed as before.
