Inserting roundings using G302 as example
With G302 the I word defines the radius of the inserted arc. Its centre point is the intersecting point of the two equidistances with an interval I to the programmed path. The positions of the equidistances are selected so that the programmed contour is retained as far as possible during the contouring operation.
Notice

No contouring radius can be inserted in tangential block transitions.
