Measuring flatness tolerance

WebA) Flatness can be considered as all points on the surface being contained within two parallel planes, the base plane and the roof plane. The measurement of distance between the planes is the overall flatness of the surface. This flatness measurement commonly carries a tolerance and may include a grade designation. 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.
