Signal address
8.2 Rigid Tapping
Brief
The rigid tapping is synchronized the tapping axis and spindle axis in the common tapping
canned cycle.
The CNC needs to detect the rotation direction signal of the spindle ensuring the direction
and processing of the cutting feed during the rigid tapping (during performing G74 and G84).
Performance processing:
Spindle rotates
→
Z axis feed tapping
→
sending the M05 stop code to spindle
