There are several Drilling Cycles available:
3. 1. 1 Drilling Cycle

This cycle is used for normal drilling. Cutting feed is
performed to the bottom of the hole. The tool is then
retracted from the bottom of the hole in rapid traverse.
By pushing [NO DWL], the following items are
displayed.
Z POINT DISTANCE
In the case G90 (Absolute = Default)
- the Z axis position of the bottom of the hole
In the case G91 (Incremental)
- the distance from point R to the bottom of the hole
R POINT DISTANCE
In the case G90 (Absolute = Default)
- the Z axis position of point R level
In the case G91 (Incremetal)
- the distance from the initial level to point R level
