Inserting of chamfers
Under G301 the I-word defines the distance between the corner point of the programmed contour and the respective intersecting point of the inserted straight line with the contour elements. If one or both the contour elements are circular arcs, this distance is considered as chord length.
If a given size of the insertion radius or the chamfer results in a direction reversal of one or both contour elements, then an error message is output.
