Just by looking at the process I have, I notice right off the bat the chip thickness which uses in its equation Q'w or MRR on the root of the cut (radial infeed) vs what is cutting on the flanks is so drastic that without expanding the profile there is no real way to increase the "chip...
One thing I forgot to mention is that I've considered stress relieving the dies after grinding. Although I can visually see the burn from the material reports we had done which resulted in a 8 point drop in hardness at the heat affect area on the flanks. But would stress relieving result in...
