2.3 Units – Recessing
ICP contour recessing unit
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: G860_ICP / cycle: G860
Further information: "Recessing G860", Page 327
Contour form:
DQ: Number of recess cycles
DX, DZ: Dist.to subsequent recess in X, Z direction (DX = radius
value)
DO: Flow (with parameters Q = 0 and DQ > 1)
0: Complete roughing/finishing – rough-machine all
recesses, then finish-machine all recesses
1: Single roughing/finishing – machine each recess
completely before machining the next one
Cycle form:
I, K: O-size X and Z
SX, SZ: Cutting limit in X and Z (default: no cutting limit;
diameter value = SX)
ET: Recess depth per infeed
P: Cut. width – infeeds <= P (no input: P = 0.8 * cutting width
of the tool)
E: Finishing feed
EZ: Delay after recessing path (default: time for one spindle
revolution)
D: Rev. on recessing floor
Q: Roughing/Finish – process variants
0: Roughing and finishing
1: Only roughing
2: Only finishing
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
1: Before finished contour
2: Stops at safety clear.
