I, K: End point which is approached at the end of
the cycle – except for H=3 or 4 (I diameter
value)
O: Feed rate reduction – default: 0
nÿ O=0: No feed rate reduction
nÿ O=1: Feed rate reduction active
During residual finishing (G890 – Q4), the
CNC PILOT, checks whether the tool can
access the contour recess without collision.
The tool parameter ”width dn” is the basis
of this collision check.
