G-Code, CAD, and CAM discussions / End Mill Engraving

« on: May 13, 2008, 11:26:31 AM »

I am engraving letters into stainless steel to a depth of 1/32 inch.  The Endmill I'm using has radiused corners to minimize burrs, but I still want to apply a small bevel to the cutout edges by making an offsetting cut at about .005 deep to take advantage of the rounded corner of the endmill.  (I can't change endmills on my Taig setup without loosing the 0.00 surface z origion point, as well as the extra time required to change tools.  What G code should I use to do this?  What about G52 offset to move the center of the cut outside the left and right edges?
