– For threads requiring multiple machining operations for their production
– For production processes requiring a defined thread starting position
Conversely, when machining multiple threads one after the other,

: Command: Tapping
The hole is defined by the drilling depth and the thread lead.
Effective:
: Command: Tapping retraction
This movement is described with the same lead as the
movement. The direction of rotation of the spindle is reversed
automatically.
Effective:
: Drilling depth (end point of the thread in Cartesian coordinates)
: Thread lead in X direction
: Thread lead in Y direction
: Thread lead in Z direction
