The command DISC is not evaluated.

The intersection is determined by extending the offset curves of the two participating blocks

and defining the intersection of the two blocks at the corner in the plane perpendicular to the

tool orientation. If no such intersection is available, a circle is inserted.

If an intersection is found in the plane perpendicular to the tool, this does not mean that the

curves also intersect in space. Rather the curves in the direction of the tool longitudinal axis

are considered, which are generally a certain distance apart. The positional offset is

eliminated over the entire block length in direction of the tool.

The way this offset is processed in tool direction at outside corners is the same as for inside

No intersection procedure

The intersection procedure is not used when at least one block containing a change to the

tool orientation was inserted between the traversing blocks in question. In this case a circle

is always inserted at the corner.

Blocks without traversing information

Blocks without relevant traversing information (neither tool orientation nor position of

geometry axes are changed) are permissible. The intersection procedure is applied to the

adjacent blocks as if these intermediate blocks did not exist. In the same manner, tool

direction motions in the tool direction may also be programmed in intermediate blocks.
