SECTION 7 FIXED CYCLES
6. Grooving/Drilling Compound Fixed Cycle
6-1. Longitudinal Grooving Fixed Cycle (G73)
[Function]
In the G73 mode, a grooving cycle is performed as shown below.
LE33013R0300900190001
[Programming format]
G73 X__ Z__ I__ K__ D__ L__ F__ E__ T__
X : X coordinate of target point
Z : Z coordinate of target point
I : Shift amount in X-axis direction (as a diameter; if no I word is specified the control assumes
I = 0)
K : Shift amount in Z-axis direction (if no K word is specified the control assumes K=0)
D : Depth of cut (infeed amount)
L : Total infeed amount for tool withdrawal motion (as a diameter; tool sequence is not performed
when L word is not specified.)
D
A
: Retraction amount "a" is specified. When no DA word is specified, the amount set with the
optional parameter (long word) No. 7 is used as the retraction amount. This applies both in
the G94 and G95 modes.
E : Duration of dwell motion when target point on X-axis is reached
(Command unit is the same as for an F word in the G04 mode.)
If no E word is specified, this sequence is not performed.
