I've called my local heat treat facility 3 times attempting to find someone who can help me out, unfortunatly there must be only 1 guy and he is never in his office, so I am turning here for some answers. I have a few parts that will be machined out of D2. The part is roughly 5.5" OD with a 3" bore. Its 0.625 thick. I plan on grinding it post heat treat in order to meet dimensional tolerances. I just need to know how much extra stock I should leave for a worse case scenario. I can't afford to scrap these parts.
Do I leave .0005"? .005"? .05"? On all dimensions. I don't want to be grinding on these to long but I would be screwed if they came back from heat treat as scrap.
I understand it "depends" on a lot of factors. I just need a ball park worse case scenario.
Thanks!
