OK - so how do I determine which side of my drawn lines gets the
compensation?
If I understand tool diameter compensation correctly, it is not designed
to
compensate for the tool radius but more designed to compensate for
slight variations
in tool diameter due to sharpening.
To profile a part, offset your cut line vector by the tool radius either
to the left or
right, depending on if you want to cut on the inside or outside. Save
the offset
vectors to a dxf and send that to Mach2.
Some of the smarter CAM programs automatically generate a toolpath that
is offset
by the tool radius and some make you do the offset manually. Artcam
does it
automatically. On more complex parts I prefer to do it manually. I
have more control
over the final outcome that way.
