SINUMERIK 840D/840Di/810D/FM-NC Programming Guide Advanced (PGA) – 04.00 Edition
Programming example
No infeed is to take place at reversal point 1. At
reversal point 2, the infeed is to start at a distance of
ii2 before reversal point 2 and the oscillating axis is
not to wait at the reversal point for the end of the
partial infeed. Axis Z is the oscillating axis and axis X
the infeed axis.
