We often turn a part, heat treat it, and then grind it to the final dimension.  Is there a proper way to show on a drawing the dimension the part should be turned down to in the lathe so the machinist and QC can know what it should be coming out of the lathe AND also show the final dimension after the grinding step on the same drawing?

I really don't want to double the number of drawings we have by creating one for the lathe and another for the grinding step.
