Chamfering at any angle or corner rounding is performed automatically by adding ",C_" or ",R_" to
the end of the block to be commanded first among those command blocks which shape the corner
with lines only.

Function and purpose
The corner is chamfered in such a way that the positions produced by subtracting the lengths
commanded by ",C_" from the imaginary starting and final corners which would apply if no
chamfering were to be performed, are connected.
