Taping Cycle Diagram
The sequence of actions is as follows:
1. Quickly locate it to the hole (X Y, but the tool maintains the original height)
2. Quickly locate it to point R
3. Tapping starts, and spindle reverses
4. Cut to the bottom position of the hole (Z) with the set cutting feedrate and spindle speed
5. Spindle stops; if P is specified, it pauses at hole bottom (P) ms
