Positioning along the X axis and Y axis, fast moving to R point. Perform drilling from R to Z. When arrived
at the bottom of the hole, suspend execution and fast moving back.
When G86 code section of the middle finger in the same program timing and M code, the positioning action
of M code execution at the same time, and then go to the next drilling movement. When specified repetitions K,
only in the first hole M code, the hole does not perform M code later.
When in a fixed loop program period specified in the tool length offset (G43 G44 G49), while positioning to
the R and offset.
