illing in C axis
"ICP tapping, C axis" unit
The unit machines a single tap hole or a tapping pattern on the face or
lateral surface. Using ICP, you define the tap holes as well as further
details.
Unit name: G73_ICP_C / Cycle: G73 (see page 328)
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.
