When the cycle is performed using G77, a skip signal can be input to
terminate the cycle. When a skip signal is input, the current operation
sequence is interrupted or completed, then the cycle is terminated.
The following shows how the system operates when the skip signal is
input during each operation sequence.
D When the skip signal is input during operation sequence 1 or 4 (cutting
feed specified by I or J), cutting is stopped immediately and the tool
returns to the X (Z) coordinate at which the cycle started.

D When the skip signal is input during operation sequence 2 or 5 (dwell),
dwell is stopped immediately and the tool returns to the X (Z)
coordinate at which the cycle started.
D When the skip signal is input during operation sequence 3 or 6
(movement), the tool returns to the X (Z) coordinate at which the cycle
started after the movement specified by X (Z) is completed.

X, (Z), I, J, and K must all be specified in incremental mode.
I, J, X, and Z in canned cycles are modal data common to G75, G77, G78,
and G79. They remain valid until new data is specified. They are cleared
when a group 00 G code other than G04 or a group 01 G code other than
G75, G77, G78, and G79 is specified.
