Stock removal

Function
With the stock removal cycle, you can machine any user-programmed contour from a blank
with paraxial stock removal. The contour may contain relief cut elements. It is possible to
machine contours using longitudinal and face machining, both externally and internally. The
technology can be freely selected (roughing, finishing, complete machining). When roughing
the contour, paraxial cuts from the maximum programmed infeed depth are programmed and
residual corners are also removed parallel to the contour after an intersection point with the
contour has been reached. Roughing is performed to the programmed allowance.
Finishing is performed in the same direction as roughing. The tool radius compensation is
selected and deselected by the cycle automatically.
Before you can machine the contour, you must enter the contour.
Rounding on the contour
In order to avoid residual corners during roughing, you can enable the "Always round the
contour" function. This will remove the protrusions that are always left at the end with each
cut (due to the cut geometry). The "Round to the previous intersection" setting accelerates
machining of the contour. However, any resulting residual corners will not be recognized or
machined. Thus, it is imperative that you check the behavior before machining using the
simulation.
