Measurement of straightness and flatness
WebMar 18, 2024 · When it comes to measuring axis straightness, there are two methods available. Dial gauge The first method is used when we need accurate deviations of the … Flatness measurements require a surface plate and a height gauge, probe, or a surface of some type. We cannot measure it by simply placing the part on a surface plate or a slab and using a height gauge as this would mean we are measuring parallelism with reference to the bottom surface. See more Many applications need parts with a flat surface. No surface is perfectly flat but using GD&T, we can develop parts with a surface that is flat … See more It may seem like flatness is very similar to other geometric as well as regular tolerances in terms of the final result. So let’s do some 1:1 comparisons in order to make sure the difference is clear to everybody reading … See more Flatness with an MMC modifier can be a bit confusing since flatness is a form control. Form controls do not work with material condition … See more We show flatness tolerance on a drawing by means of a feature control frame. The feature control frame of flatness is quite straightforward. The … See more
