Number of cutting operations to be performed on finishing allowance corresponding to standard pattern (#0) of threading unit
Number of cutting operations to be performed on finishing allowance corresponding to standard pattern (#0) of threading unit
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 invalid. For thread refinishing, one cutting operation is performed as before.
