Contour recessing with direct contour input unit

The unit machines the contour defined by the parameters axially or
radially.
Unit name: G860_G80 / cycle: G860
Further information:
Contour form:
RI, RK: Oversize blank X and Z
Further parameters of the Contour form:
Further information:
Cycle form:
Q: Roughing/Finish – process variants
0: Roughing and finishing
1: Only roughing
2: Only finishing
I, K: O-size X and Z
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
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
Further forms:
Further information:
The control uses the tool definition to distinguish between radial
and axial recessing.
