2.10.6 2 1/2 D tool offset (CUT2D, CUT2DD, CUT2DF, CUT2DFD)
The 2½ D tool radius compensation should be used if, when machining inclined surfaces,
the workpiece is to be rotated, and not the tool alignment. This function is activated using
commands CUT2D, CUT2DD, CUT2DF oder CUT2DFD.
Tool length offset
The tool length compensation is always taken into account referred to the machining plane that
is not rotated and is fixed in space.
2½ D tool radius compensation for contour tools
2½ D tool radius compensation for contour tools is activated, if, together with CUT2D, CUT2DD,
CUT2DF or CUT2DFD, one of the two commands G41 (tool radius compensation left of the
contour) or G42 (tool radius compensation right of the contour) is programmed. It 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.
Note
If 2½ D tool radius compensation is not activated, a contour tool behaves like a standard tool,
which only has the first cutting edge.
2½ tool radius compensation referred to a differential tool
2½ D tool radius compensation, referred to a differential tool, is activated using theCUT2DD or
CUT2DFD commands. It should be applied if the programmed contour refers to the center point
path of a differential tool, and a tool other than a differential tool is used for machining. When
calculating the 2½ D tool radius compensation, only the wear of the radius of the active tool
($TC_DP_15) and the possibly programmed tool offsetOFFN (Page 251) and TOFFR
(Page 84) are taken into account. The basic radius ($TC_DP6) of the active tool is not taken into
account.
