When the G78 (G92, G21) cycle is executed with the single block function ON, the
cycle is not suspended halfway, but it stops after the completion of the cycle consi-
sting of sequence 1 to 4.
The S, T, and M functions that are used as the cutting conditions for the execution
of the G78 (G92, G21) cycle should be specified in blocks preceding the G78 (G92,
G21) block. However, if these functions are specified in a block independently wi-
thout axis movement commands, such designation is valid if the block is specified
in the G78 (G92, G21) mode range.
When the CYCLE START button is pressed while the cutting tool is at start point A
or chamfering completion point B, the suspended cycle is executed again from the
beginning.
If the thread cutting feed hold option is not selected, the thread cutting cycle is con-
tinued even if the FEED HOLD button is pressed during the execution of thread
cutting cycle. In this case, the operation is suspended upon completion of retraction
operation after finishing the thread cutting cycle.
