Cutoff - CYCLE92
Programming
CYCLE92 (SPD, SPL, DIAG1, DIAG2, RC, SDIS, SV1, SV2, SDAC, FF1, FF2, SS2, 0, VARI, 1, 0, AMODE)
Starting point along facing axis (absolute, always diameter)
Starting point in the longitudinal axis (absolute)
Depth for speed reduction ∅ (absolute)
Final depth ∅ (absolute)
Chamfer width or rounding radius
Safety clearance (to be added to the reference point; enter without sign)
Maximum speed at constant cutting speed
Direction of spindle rotation (values: 3 = M3; 4 = M4)
Feed to depth for speed reduction
Reduced feed up to final depth, mm/rev
Reduced speed up to final depth
Internal parameter; only the default value 0 is possible
Machining type (values: 0 = Retraction to SPD + SDIS; 1 = No retraction)
Internal parameter; only the default value 1 is possible
Internal parameter; only the default value 0 is possible
Alternate mode: radius or chamfer (values: 10000 = radius; 11000 = chamfer)
CYCLE92 is used to cut off balanced parts (for example, screws, bolts, or pipes) dynamically.
You can program a chamfer or rounding on the edge of the machined part. You can machine at a constant cutting rate V or
speed S up to a depth DIAG1, from which point the workpiece is machined at a constant speed. As of depth DIAG2, you can
also program a reduced feedrate FF2 or a reduced speed SS2, in order to adapt the velocity to the smaller diameter.
Use parameter DIAG2 to enter the final depth that you wish to reach with the cut-off. With pipes, for example, you do not
need to cut-off until you reach the center; cutting off slightly more than the wall thickness of the pipe is sufficient.
