G73 HIGH-SPEED PECK DRILLING CYCLE
N_ G73 X_ Y_ Z_ R_ Q_ F_
During a G73 high-speed peck drilling cycle, the tool feeds in to the peck distance or depth of cut, then retracts a small pre-determined distance, which is the chip-breaking process, and then feeds to the next peck, which takes the tool deeper.
