ICP recess turning unit
The unit machines the contour described by ICP axially/radially from
NS to NE. The workpiece is machined by alternate recessing and
roughing movements.
The unit machines the contour described in the FINISHED PART
section axially/radially from NS to NE. Any Auxiliary contour
defined in FK will be used.
Unit name: G869_ICP / cycle: G869
Further information: "Recess turning cycle G869", Page 331
Contour form:
X1, Z1: Start point blank – evaluation only if no blank was
defined
RI, RK: Oversize blank X and Z
SX, SZ: Cutting limit in X and Z (default: no cutting limit;
diameter value = SX)
Further parameters of the form Contour:
Further information: "Contour form", Page 80
Cycle form:
