4.4 Tapping

There are two tapping cycles available in the control:

tapping with floating tap holder and

rigid tapping.

Tapping with floating tap holder is possible for both analogue and BCD-coded spindle-speed output.
Rigid tapping is only possible for analogue spindle-speed output.

The tapping cycle is defined in the NC-program and can be called with CYCL CALL (M03). Tapping is
adjusted to the dynamic behaviour of the machine by machine parameters.
