Thickness, Parallelism and Flatness | Precision Grinding, Inc.

Some drawings ask for a part to be flat in the restrained condition. This is not true flatness but the surface is intended to be flat enough to be bolted or clamped in a flat condition. Normally, if a flatness of 0.003″/ft is quoted, then multiply the diagonal dimension of the part in feet by 0.003″ to get the total flatness tolerance.
