The format for the G86 cycle is:
G86X__Z__R__P__F__L__;
Where : Is :
X specifies location of thehole.
Z defines the holebottom.
R defines the Rpoint level.
P defines the dwellperiod at holebottom.
F defines the cuttingfeedrate.
L defines the numberof times thedrilling cycleis repeated.
See page 26-7 for a detailed description of these parameters.
Important: The programmer or operator must start spindle or live tool
rotation.
