Nibbling can be performed in a block between an M-code for nibbling
(M12) and an M-code for nibbling cancel (M13). These M-codes are
specified by parameters.
Linear nibbling can be done by commanding G01 in the nibbling mode,
while circular nibbling can be done by commanding G02 and G03 in the
nibbling mode.
The tool diameter cannot be offset by G01, G02, G03 commands.
Accordingly, these commands are used together with cutter compensation
commands (G40, G41, G42) when nibbling is done by offsetting a
continuous straight line or circular arc leftwards or rightwards by the tool
diameter.
