Hi group. I have a bunch of 6061 parts to do for aerospace company and just wandering if I can get some guidance about stress reliving. Parts vary from 6" X 6" X 1.5" to 24" X 12" X 3" but after they are done there is almost nothing left. Full of pockets, ribs and holes. Wall thickness from 0.03" to 0.08". I want to complete finish it from 5 sides on 5 axis mill and than do the other side. From your experience will it work or I will get lots of deflection even after stress reliving? And another question is how do you do that? I put it in a furnace at 350 for
4 hours as I was told by one person but other people had different ideas. Someone told me to dip it in nitrogen. Thanks in advance for any help. Jerry- posted
