Machining type
You can select the machining mode (roughing or finishing). During contour roughing, parallel
cuts of maximum programmed infeed depth are created. Roughing is performed to the
programmed allowance.
You can also specify a compensation allowance U1 for finishing operations, which allows
you to either finish several times (positive allowance) or to shrink the contour (negative
allowance). Finishing is performed in the same direction as roughing.
