Measure the thickness of the part. Let's say it was .497. From the maximum part thickness of .510, subtract the actual thickness. In our case we would get .013 and that is the flatness allowed at that thickness. If the part was made at its largest allowable size, .510, there would be not flatness allowance. medway council penalty charge
