Fig. 5-24: Removing tool path compensation
Removing tool path compensation on an arc will not cause an error to be
issued, but it will cause unpredictable contour errors. To avoid violations
of the contour end point, the end point of tool path compensation must be
selected in such a way that the tool is located completely within the quad-
rant which is opposite the contour corner.

Fig. 5-25: Contour end with tool path compensation
If the end point of the tool path compensation is moved into an inside cor-
ner with closed contours, a contour violation would result at the start of
the contour (see Fig. 5-26).
