I am programming a aerospace part in aluminum 7050. Okuma mu6300. Part is held in dovetail and is tabbed to finish. This pocket is 2. x 6. x 2.0 deep. One wall is .06 thick and is pushing out when finishing. I cannot get it to size without going negative stock to leave. I have tried roughing and finishing in 2 steps roughing in 1 step, leaving wall at .140 and finishing in steps. Both ways wall is not flat and is over and on size in different places. I have tried a mix of 3/4 sharp 4flt and 1/2 Em .125r. Anyone have any tips for these kinds of walls. For example EM diameter, flute count, corner radius size, amount for finish pass etc.
