Automatic Any-Angle Chamfering

When cutting a workpiece, it is often necessary to chamfer the sharp (C-chamfer or R-chamfer)
corners and edges.
programming chamfering using G01, G02 and G03 commands is not easy.
chamfering function can program chamfering easily.

With the program above, the cutting tool moves from point A to point J in the sequence A, B, D,
E, G, H, I and J, thus accomplishing chamfering of B-D, E-G and H-I.
[Supplement]
Angle commands (A) are designated in reference to the Z-axis.
If chamfering is required on edges having an angle other than 90°,
