I did another test of the slot. The previous attempt the slot ended up being 0.950". I tracked down that problem to using a 1/2" EM in the program but the machine had a 12mm EM. That accounted for most of the 0.050" too small. However I did the job again using an adaptive tool path and 0.15" step downs. See picture and you can see the milling lines showing the adaptive pattern. Results however were still a bit small. The slot measures 0.995" wide at the top and 0.990 at the bottom. It should be 1.000".
I have a couple ideas - #1 don't use adaptive instead use straight slot milling. #2 just run the program again and see if a spring pass removes that remaining 0.005 to 0.010". Thoughts ?
