As shown above, the format is divided into the hole machining mode, hole positioning data, hole
machining data, No. of repetitions, spindle rotation speed, synchronization changeover (or spindle
rotation speed at during retract), positioning axis in-position width and drilling axis in-position width.
Detailed description
(1) Data outline and corresponding address
(a) Hole machining mode
(b) Hole position data
(c) Hole machining data
(d) No. of repetitions
(e) Synchronization changeover : Command for selecting synchronous/asynchronous
(2) If M00 or M01 is commanded in the same block as the canned cycle or during the canned cycle
mode, the canned cycle will be ignored. Instead, M00 and M01 will be output after positioning.
The canned cycle will be executed if X, Y, Z or R is commanded.
