Circumferential speed reduction ratio at
cutting end of a very-deep-hole drilling
cycle (through hole)
Program type M
Conditions After movement stop
D59
Unit %
Setting range 0 to 100
Set the circumferential speed reduction ratio at cutting end of a very-
deep-hole drilling cycle (through hole) during the point machining.
If the circumferential speed during drilling is S, the circumferential speed
S’ at cutting end is calculated using the following calculation expression:
S’ = S ×
D59/100
The circumferential speed is reduced to S’ by “speed reduction distance
immediately before the hole bottom” (hb specified in the program).
hb
Distance to the
hole bottom
Automatic setting ratio of axial cutting feed
rate during chamfering
Program type M
Conditions After movement stop
D60
Unit
%
Setting range 0 to 100
Set the ratio between automatic setting value for the feed rate in the axial
cutting and that in the radial cutting during chamfering in the point
machining.
