- 8. A note in the comment section of a title block mentions that all faces should have a +.10 tolerance before heat treatment. The machinist follows the instructions but for diameters he leaves a tolerance of +.20. Why? O A. The machinist may have committed an error, and the part must be returned prior to heat treatment. OB. Diameter dimensions usually change by twice as much as the faces. OC. The tolerances for diameters aren't as critical as face tolerances. D.
