Height of the third R-point
The height of the R-point during point machining is basically D41, however
it is changed to D42 under the following conditions.
Number of incomplete threads in tapping
cycle for piped screw
Program type M
Conditions Immediate
D43
Unit 1 thread
Setting range 0 to 9
To set number of incomplete threads in tapping cycle for piped screws
(PT, PF, PS). In tapping, internal thread is tapped extra for the depth of
(D43 × pitch) in the direction of Z.
This is also used as an element for automatically determining hole-drilling
depth (HOLE-DEP) in the automatic tool development of the tapping unit.
