Parameters
Parameter
Data type
Description
SPD
REAL
Starting point along facing axis (absolute, always diameter)
SPL
REAL
Starting point in the longitudinal axis (absolute)
DIAG1
REAL
Depth for speed reduction ∅ (absolute)
DIAG2
REAL
Final depth ∅ (absolute)
RC
REAL
Chamfer width or rounding radius
SDIS
REAL
Safety clearance (to be added to the reference point; enter without sign)
SV1
REAL
Constant cutting rate V
SV2
REAL
Maximum speed at constant cutting speed
SDAC
INT
Direction of spindle rotation (values: 3 = M3; 4 = M4)
FF1
REAL
Feed to depth for speed reduction
FF2
REAL
Reduced feed up to final depth, mm/rev
SS2
REAL
Reduced speed up to final depth
PSYS
INT
Internal parameter; only the default value 0 is possible
VARI
INT
Machining type (values: 0 = Retraction to SPD + SDIS; 1 = No retraction)
PSYS
INT
Internal parameter; only the default value 1 is possible
PSYS
INT
Internal parameter; only the default value 0 is possible
AMODE
INT
Alternate mode: radius or chamfer (values: 10000 = radius; 11000 = chamfer)
Function
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.
