Hey I am having trouble with surfacing in a program im writing for a
VMC.

the program is at www.stcrock.com/Profiling.MC9

What I am trying to do is cut a radiused slot within a radiused slot,
my issue is that the cutter begins cutting a little inside the lines,
and finishes before it touches the lines on the other side, resulting
in the slot being too narrow. How can I solve this problem?


I was able to control it, here's what I did with your file...real easy.

I went into your last operation, the cut I think your talking about, and I
added 2 check surfaces, by selecting "select" check surf button and picking
solids on the menu and faces. Then I picked the two faces on either end of
your cut and put in a check value of MINUS -.017.
After a regen I looked in the top view and the cut was .125 approx from
the edge. I close zoom and an adjustment would make it perfect.
Basically using check surfs to remove more material.

Now, if the other end isnt perfect, no problem.
Simply put one side where it belongs, then edit the amount till the other
end is where you want it. Split the difference and use that value.
Then right click on your cut and pick transform cut, and make a tranformed
cut with the same value you just used in the last sentence.

An alternative way would be to extend the cut, then use a 2 dimensional
square drawn above the part and use tool containment. Use center, and draw
your box half the tool in each way.

Prolly a hundred more ways.

I don't see why any of that should be needed.
What's really being done wrong?
Recheck all options, stock, finish thick, tool definition, etc.
