13.7 Corner Chamfering/Corner Rounding I
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.
13.7.1 Corner Chamfering " ,C_ "
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.
Command format
N100 G01 X__ Y__ ,C__ ;
N200 G01 X__ Y__ ;
,C
: Length up to chamfering starting point or end point from imaginary corner
Chamfering is performed at the point where N100 and N200 intersect.
