2.3 Units—Recessing
"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 program
section axially/radially from "NS to NE". Any auxiliary contour defined
in FK will be used.
Unit name: G869_ICP / Cycle: G869 (see page 286)
The Steuerung uses the tool definition to distinguish between radial
and axial recessing.
Turning depth compensation RB: Depending on factors such as
workpiece material or feed rate, the tool tip is displaced during a
turning operation. You can correct the resulting infeed error with the
turning depth compensation factor. The value is usually determined
empirically.

H Type of retraction at end of cycle
 0: Return to starting point
 Axial recess: First Z, then X direction
 Radial recess: First X, then Z direction
 1: Positions in front of the finished contour
 2: Retracts to safety clearance and stops
