the spindle stops, and the tool is moved always from the machined surface of the workpiece and
retracted with the direction that set by P3 in User parameter.
Format:
G76 X_ Y_ Z_ R_ Q_ P_ F_ L_ ;
X_Y_ : Hole position data.
Z_ :
The distance from point R to the bottom of the hole.
R_ :
The distance from the initial level to point R level.
Q_ :
Shift amount at the bottom of a hole.
P_ :
Dwell time at the bottom of a hole. Unit:s.
F_ :
Cutting feedrate.
L_ :
Number of repeats (if required) .
G76(G98)
G76(G99)
Warning: Q(shift at the bottom of a hole) is a modal value retained within canned cycles. It must be
specified carefully because it is also used as the depth of cut for G73 and G83
.
Direction of shift after oriented spindle stop is set by P3 in User parameter.
