18.5.7 Compensation at inside corners
Intersection
If two consecutive blocks form an inside corner, an attempt is made to find a point at which the two equidistant
paths intersect. If an intersection is found, the programmed contour is shortened to the intersection (first block
shortened at end, second block shortened at beginning).
Figure 18-28 Example of a shortened contour
No intersection
In certain cases, no intersection is found between two consecutive blocks for inside corners (see figure below).
