General information

Function
You can create and machine simple or complex contours with the "Contour turning" cycle. A
contour comprises separate contour elements, whereby at least two and up to 100 elements
result in a defined contour.
You can program chamfers, radii, undercuts or tangential transitions between the contour
elements.
Programming
The programming for stock removal is as follows:
1. Enter finished-part contour
2. Stock removal along the contour (roughing)
3. Stock removal along the contour (finishing)
206
You build up the finished-part contour gradually from a series of different contour
elements.
The contour is machined longitudinally, transversely or parallel to the contour.
If you programmed a finishing allowance for roughing, the contour is machined again.
