Re: [CAD_CAM_EDM_DRO] Tool Comp G41,G42

The real bonus to having G41 & G42 dia offsets (via a "T" code) is not so
much the offsetting of the tool per se, as it doesn't take a real rocket
surgeon to offset a toolpath 1/4" for a half inch mill (at least, not with
today's CAD programs). No, the real beauty of G41 & G42 is when you run
the program that's expecting a .500" dia endmill, and you only have one
that's been sharpened down to .468", or ,442", etc. That way, you always
draw your part to scale, and edit the tool offsets as dictated by the tool
size. (This assumes you're running a program over and over, at different
times).
