Re: Z-differences between machined surfaces of equal height in model
hi face and dial the part before begining, then run a few prefinishes and dial the part between them
also, after removing the part from machining fixture, clamp it in another manner, with minimal holding force, and dial it again
like this, you should find if deformation occurs during machining, or after removing it from the fixture
it may be required to change a bit your model, in order to have a flat surface, that you may use to dial on it; is possible to entirely avoid these flat surfaces, and dial directly on a 3d complex shape, but this procedure is a bit more time consuming, and it's precision may be too high for finding the flex source; normally, i use it for surface prelevation of complex shapes, so ....
