Motion commands
4.18 Tapping with compensating chuck (G63)
Fundamentals
180 Programming Manual, 11/2006, 6FC5398-1BP10-2BA0
Parameters
G63
Tapping with compensating chuck.
X Y Z
Drilling depth (end point) in a Cartesian coordinate
Note
G63 is non-modal.
The last programmed interpolation command G0, G1, G2, etc., is reactivated after a block
with programmed G63.
Feedrate
Note
The programmed feed must match the ratio of the speed to the thread lead of the tap.
Thumb rule:
Feed F in mm/min = spindle speed S
in rpm x thread lead in mm/rev
Both the feed and the spindle speed override switch are set to 100% with G63.
