Advanced CMMs (Coordinate measuring machines) can inspect flatness … WebThis 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. See example illustrations below.

WebFeb 12, 2024 · The flatness tolerance zone is a 3D tolerance zone, meaning that when you are checking flatness of a surface, you are checking the amount of variation up and down … WebFlatness can also be measured using a dial gauge. As shown in the above image, to measure flatness using a dial gauge, drill a through-hole in the surface plate. And dial gauge probe is passed through it. To sum up, Flatness tolerance controls the flatness of a surface regardless of any datum feature. It makes a 3-dimensional tolerance zone. red sleepshirt
