When slot side compensation is on, slots with parallel sides are machined even if the slot width
is larger than the tool diameter.
The slot contour must not be programmed for machining purposes, but the imaginary center-
point path of a bolt guided in the slot; whereby the bolt must move along every side. The slot
width is determined by parameter D.
Note
Selecting slot side compensation
The slot side compensation selection depends on the transformation type.
General procedure
The basic programming procedure is as follows:
● Select work offset for cylinder surface transformation (e.g. offset the zero point on the center
point of the cylinder end face)
● Position the Y axis (Y axis must be positioned prior to cylinder surface transformation
because it is defined differently after transformation)
● Activate cylinder surface transformation
● Select work offset for machining on the developed cylinder surface (e.g. shift zero point to
the zero point on the workpiece drawing)
● Program machining operation (e.g. enter contour and path milling)
● Deactivate cylinder surface transformation
The programmed cylinder surface transformation is simulated only as developed peripheral
surface.
Note
The work offsets active prior to selection of cylinder surface transformation are no longer active
after the function has been deselected.
