2.5 Units—Drilling in C axis
"Tapping, face" unit
This unit machines a single tap hole on the face of the workpiece.
Unit name: G73_Gew_Stirn_C / Cycle: G73 (see page 296)
Use the retraction length for floating tap holders. The cycle
calculates a new nominal pitch on the basis of the thread depth, the
programmed pitch, and the retraction length. The nominal pitch is
somewhat smaller than the pitch of the tap. During tapping, the tap is
pulled away from the chuck by the retraction length. With this method
you can achieve higher service life from taps.
JB Minimum hole depth
B Retraction distance
RI Internal safety clearance: Distance for reapproach inside
the hole (default: safety clearance SCK).
RB Return plane (default: return to the starting position or to
the safety clearance)
