G73 - Peck Drill with Chip Break Drill Cycle
G73 sets chip break drilling as the modal drill cycle.
Default—Yes
Modal—Yes
Cancels G74, G80, G81, G82, G83, G84, G98, G99
The tool motion for the chip break drill cycle is illustrated in Figure 2–9. Tool Motion for
G73 Chip Break Drill Cycle, on page 2 - 22. This cycle requires programming X or Z, R
(Retract Clearance Plane), and Q. G73 causes the tool to feed by the amount
programmed in Q, then rapid back an incremental amount, A (2.5 mm). Next the tool will
rapid to a distance slightly above (2.5 mm) the last infeed depth, then feed another Q
distance into the part. This sequence repeats until the tool reaches the programmed Z
depth. Program G99 (Drill Cycle R Plane Return) to move the tool back to the R plane.
The following figure illustrates tool motion for G73 chip break drill cycle. The short
broken lines represent rapid moves; the long broken lines represent feed moves.
