Note
Both functions G331/G332 are modal.
After G332 (retraction), the next thread can be tapped with G331.
Equipment required: position-controlled spindle with position measurement system.
The spindle must be prepared for tapping with SPOS/SPOSA. It does not work in axis
operation, but as a position-controlled spindle, see section Feed control and spindle
movement, "Position-controlled spindle operation".
