Precondition
With regard to technology, tapping without compensating chuck requires a position-controlled
spindle with position measuring system.

Tapping without compensating chuck is programmed using the G331 and G332 commands.
The spindle prepared for tapping can make the following movements in position-controlled
operation with distance measuring system:
• G331: Tapping with thread lead in tapping direction up to end point
• G332: Retraction movement with the same lead as G331
Right-hand or left-hand threads are defined by the sign of the lead:
