Inserting a rounding

Under G302 the I-word defines the radius of the inserted circular arc. Its center point is the intersecting point of both the equidistant with an interval I to programmed path. The positions of the equidistant will be fixed by the demand, that the programmed contour during the rounding should be keep as far as possible.

In tangential block transitions, as a rule, no contouring radius can be inserted.
