3.1 Units—Drilling in Y Axis
"ICP tapping, Y axis" unit
The unit machines a single tap hole or a hole pattern in the XY or YZ
plane. Using ICP, you define the tap holes as well as further details.
Unit name: G73_ICP_Y / Cycle: G73 (see page 296)
Retraction length L: Use this parameter for floating tap holders. The
cycle calculates a new nominal pitch on the basis of the thread depth,
the programmed pitch, and the “retract 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 the taps.
