Thefollowing can be specified:● Number of infeed steps constant or decreasing (via programmable degression factor)● Chip breaking without lifting or swarth removal with tool retraction● Feedrate factor for 1st infeed to reduce the feedrate or increase the feedrate (e.g. if ahole has already be predrilled)● Dwell times● Depth in relation to drill shank of drill tip
