5.2 Basic Motions in Canned Cycle
In general, the canned cycle is composed of the following six motions.
Motion 1 : Positioning (at rapid feed) to the drilling position (X/Y)
Motion 2 : Positioning to R point (at rapid feed)
Motion 3 : Hole machining (cutting feed)
Motion 4 : Machining at the bottom of hole
Motion 5 : Relief to R point (at rapid feed/cutting feed)
Motion 6 : Positioning to initial point (at rapid feed)

The system stops upon completion of the motion 1, 2 or 6 in the single block operation.
(Note) Temporary stop range in tapping cycle (G74, G77, G78, G84, G177, G178).
(1) During the motion 1, 2 or 6 in the tapping cycle, a temporary stop is available.
(2) During the motions 3 through 5 in the tapping cycle, a temporary stop is forbidden.
If such a stop is forcibly done (by pressing the HOLD switch or changing to the manual
mode), the system stops upon completion of the motion 5.
If the RESET key is pressed during the motion 3 through 5, the system also stops after
completion of the motion 5.
