8.13 2D tool compensation (CUT2D, CUT2DF)
8.13 2D tool compensation (CUT2D, CUT2DF)
Function
With CUT2D or CUT2DF you define how the tool radius compensation is to act or to be
interpreted when machining in inclined planes.
Tool length compensation
The tool length compensation generally always refers to the fixed, non-rotated working
plane.
2D tool radius compensation with contour tools
The tool radius compensation for contour tools is used for automatic cutting-edge selection
in the case of non-axially symmetrical tools that can be used for piece-by-piece machining of
individual contour segments.
Programming
CUT2D
Or
CUT2DF
2D tool radius compensation for contour tools is activated if either of the two machining
directions G41 or G42 is programmed with CUT2D or CUT2DF.
Note
If tool radius compensation is not activated, a contour tool will behave like a standard tool
with only the first cutting edge.
Parameters
CUT2D
CUT2DF
CUT2D is used when the orientation of the tool cannot be changed and the workpiece is
rotated for machining on inclined surfaces.
CUT2D is generally the standard setting and does not, therefore, have to be specified
explicitly.
Cutting-edge selection with contour tools
Up to a maximum of 12 cutting edges can be assigned to each contour tool in any order.
