Then, the C-axis is clamped.
When the return point of cutting is set at the cycle start point, the axes are positioned at
point Z

2) When slide hold is designated during the execution of the steps Q
as follows.
Step Q
3
The M-tool spindle and the feed axes are stopped at that position.
The M-tool spindle is then returned to the cutting start point in synchronized cutting feed while
it rotates in the direction opposite to that it had been rotating in, then enters the slide hold state.
Step Q
4
The axes are returned to the cutting start point in synchronized feed, and the slide hold state is
established.
3) The dry run function is not effective during the execution of steps Q
4) The M-tool spindle is stopped when the synchronized tapping cycle is complete.
8-15-2. Reverse tapping cycle (G179)
Axis motion is the same as in the forward tapping cycle but the M-tool spindle rotates in the reverse
direction in steps Q
while being rotated in the forward direction.
