When the above specification is added to the end of a block that specifies
linear interpolation (G01) or circular interpolation (G02 or G03), a
chamfering or corner rounding block is inserted.
Blocks specifying chamfering and corner rounding can be specified
consecutively.
After C, specify the distance from the virtual corner point to the start and
end points. The virtual corner point is the corner point that would exist
if chamfering were not performed.
