WebAfter this is accomplished, we use an indicator to measure the out-of-flatness of the "top"surface and, in effect, measure the surface against itself. If we want to measure the parallelism of one side (we'll say the bottom) to the other side (the top), we can rest the bottom on a surface plate and compare one plane (or axis) to the other. WebMeasurements can be accurately read, with the scale (or digital meter), the base of the scale, and the surface gauge being integrated. Using a dial indicator holder, a lever-type dial gauge can be attached to measure parallelism, flatness, and straightness. Measurements need a surface plate to be used as a reference.

WebJul 20, 2024 · The first method for testing a part’s flatness consists of laying the part on a CMM marble with a pre-defined flatness. Then, using a feeler gauge, which is made of strips with already characterized thicknesses, we try to insert strips of different thicknesses under the part. Since we know that a surface, once positioned on the marble, will ...

WebMar 18, 2024 · Straightness tolerance is a 2-dimensional GD&T callout that controls the straightness of part features. No axis can be perfectly straight. The goal is to ensure it is straight enough for the application. This callout sets a standard on how straight a feature must be along its length. Straightness can control two very different types of functions.
