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:
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:
Cycle form:
P: Maximum infeed
I, K: O-size X and Z
RB: Depth compens. for finishing
B: Offset width (default: 0)
U: Direction: – cutting direction
0: Bidirectional (in both directions)
1: Unidirectional (in direction of contour)
Q: Roughing/Finish – process variants
0: Roughing and finishing
1: Only roughing
2: Only finishing
A: Approach angle (default: opposite to recessing direction)
W: Depart.angle (default: opposite to recessing direction)
O: Recessing feed (default: active feed rate)
E: Finishing feed
H: Kind of liber. at end of cycle
0: Back to start point
Axial recess: First Z, then X direction
Radial recess: First X, then Z direction
