Tool radius compensation, CUT2DF
In this case, it is possible to arrange the tool orientation perpendicular to the inclined working
plane on the machine.
If a frame containing a rotation is programmed, the compensation plane is also rotated with
CUT2DF. The tool radius compensation is calculated in the rotated machining plane.
Note
The tool length compensation continues to be active relative to the non-rotated working
plane.
Definition of contour tools, CUT2D, CUT2DF
A contour tool is defined by the number of cutting edges (on the basis of D nos) associated
with a T no. The first cutting edge of a contour tool is the cutting edge that is selected when
the tool is activated. If, for example, D5 is activated on T3 D5, then it is this cutting edge and
the subsequent cutting edges that define the contour tool either partially or as a whole. The
previous cutting edges will be ignored.
