Common drilling
Peck drilling
G83
G87
Precautions:
1) G83 or G87 is the modal G command of the group 01, which can be cancelled by the G
command of group 01. The rest of the command words are the modal data other than the
positioning place, cycle times and the M code of the clamping index spindle.
2) Do not use the cutter compensation C in G83 or G87 command, the cutter
compensation may automatically retract when entering the drilling cycle, it may
automatically recover after drilling.
3) It is necessary to select the G18 panel when performing the G83 or G87 command.
4) Fail to perform the G83, G87 command in the G71
