<< Darrell,

The clamping sounds good, close to what I was going to do (OK, a little
better!). Sounds like multiple "contours" aren't that important? I
don't have a lot of end-mills yet, but I guess if I go slow for the
"roughing" cuts, and finish up with another profile (tool path), it will
work. I don't think MAXNC does the tool comp, (G41/G42), so as long as
I'm doing multiple contours, I can easily put the comp. in there. Do
you suggest cutting the full depth (.625) for each cut, or do I need to
do multiple passes to get the depth down? Seems like a lot to cut
(roughing) on a Sherline!

Alan,

I don't recall if this part was steel or 6061 but one trick I use on my
smaller machine is to run a 5/16" roughing end mill for the first pass,
change to a 3/8" for the finish pass. Makes for less coding work as one tool
path will do it all. Just a thought. Would work with a 7/16" rough, 1/2"
finish etc. I got no cutter comp on my stuff so I make do. Good parts are the
end result we seek.
