Hi guys. Quick question about this material relieving. We purchase 4.5" diameter Turned, Ground, and Polished because the application requires it to stay straight within a couple thou. They are about 5 ft long. We have to cut some of the top and some of the sides to create like a square boss to fit into a mating slot. This square boss is along the whole length. The problem we're facing, is that the parts seems to be warping up to .008" when we're done. It's not heat, because the part is very cool to the touch and all the heat is in the chip when milling. Is this material still relieving and if so, is there a good way to combat this?
