- Miscellaneous function
When the G88 command and an M code are specified in the same block,
the M code is executed at the time of the first positioning operation.
When L is used to specify the number of repeats, the M code is
executed for the first hole only; for the second and subsequent holes,
the M code is not executed.
- Tool length compensation
When a tool length offset (G43, G44, or G49) is specified in the canned
cycle, the offset is applied at the time of positioning to point R.
- Axis switching
Before the drilling axis can be changed, the canned cycle must be
In a block that does not contain X, Y, Z, R, or any other axes, drilling is
Specify R in blocks that perform drilling. If it is specified in a block
that does not perform drilling, it cannot be stored as modal data.
Do not specify a G code of the 01 group (G00 to G03 or etc.) and G88
in a single block. Otherwise, G88 will be canceled.
- Tool offset
In the canned cycle mode, tool offsets are ignored.
