Corner Rounding and Chamfering
Corner rounding and chamfering may be used to shorten and make it easier to write programs. With this
utility the end points of chamfers and radii are automatically calculated. For chamfers ,C with the length
of the chamfer indicated is used. For radii a ,R with the size of the radius indicated. The chamfering or
corner rounding block may be inserted between two linear or G01 blocks. These two blocks specify a
corner of the intersection of the two linear moves. The corner rounding and chamfering function
interprets this as the corner and automatically calculates the start and end points of the radius or chamfer
desired. The corner the rounding function will figure the radius of a circle tangent to that corner.
Below gives a print with the corner dimensions. What is desired is .06 and .5 radii on the top and .06 and .2
chamfers on the bottom.
