11.2 Canned cycle
General
Canned cycles make it easier for the programmer to create programs. With a canned
cycle, a frequently-used machining operation can be specified during a signgle block
with a G function; without canned cycles, normally more than one block is required.
During addition, the use of canned cycles can shorten the program to save memory.
One canned cycle consists of a sequence of six operations:
Operation 1: Positioning a hole
Operation 2: Rapid traverse up to R level
Operation 3: Hole machining
Operation 4: Operation at the bottom of a hole
Operation 5: Retraction to point R level
Operation 6: Rapid traverse up to the initial point
Operation sequence of canned cycle is as follows:
The following canned cycles require spindle control:
Reverse tapping cycle G74
）
Fine boring cycle G76
）
Tapping cycle G84 Boring cycle G86
Back boring cycle G87 Boring cycle G88
For spindle control, the following normal miscellaneous functions are used:
See the description of the miscellaneous functions.
M03
： CW spindle rotation
M04 ： CCW spindle rotation
M05 ： Spindle stop
M19 ： Spindle orientation
When the rotation direction of the spindle is to be switched from one direction to the
other (for example, when M04 is output during M03 operation), a parameter can be
specified whether to send M05 at the time switching).
