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.
