The format for the G83 cycle is:
G83X__Z__R__Q__F__L__;
Where : Is :
X specifies location of the hole.
Z defines the hole bottom.
R defines the R point level.
Q defines the infeed amount for each step into the hole.
F defines the cutting feedrate.
L defines the number of times the drilling cycle is repeated.
See page 26-7 for a detailed description of these parameters.
Important: The programmer or operator must start spindle or live tool
rotation.
