Cycle run
1 Calculate the proportioning of cuts (infeed), taking the parameter J
into account.
„ J=0: The cutting geometry is taken into account. This may result
in the use of different infeeds for the longitudinal and transverse
directions.
„ J>0: The same infeed is used for both the longitudinal and the
transverse direction.
2 Approach workpiece on paraxial path for first pass from X, Z.
3 Machine the workpiece according to the calculated proportioning
of cuts.
4 Return and approach for next pass.
5 Repeat 3 to 4 until the defined area has been machined.
6 Return to starting point on paraxial path.
The cycle parameter workpiece blank oversize J is
available as of NC software versions 507 807-16 and
526 488-08. With earlier software versions, the cycle
starts the machining operation from the current tool
position.
