The tool motion for the chip break drill cycle is illustrated in Figure 4–29. G83 Peck Drill
Cycle, on page 4 - 71This cycle requires programming X or Z, R (Retract Clearance
Plane), and Q. This cycle causes the tool to feed by the amount programmed in Q, then
rapid back to the R plane. Next the tool rapids to a distance slightly above (2.5mm) the
last infeed depth, then feeds another Q distance into the part. This sequence repeats until
the tool reaches the programmed Z depth.
The following figure illustrates tool motion for G83 peck drill cycle. The short broken lines
represent rapid moves; the long broken lines represent feed moves.
