WebJul 8, 2024 · You would start anywhere within the length of the part and measure along 1.000" from there, and still should conform to a straightness of 0.005". However Zeno, you point out that your process ensures that a perfect bow is produced, which means that the radius is uniform acorss the length of the part. WebAug 24, 2013 · Then, the distance A-B is the roughness, and the distance A-C is the flatness (but depending on the values given, A-C could also be the "waviness"). You'd have to look at the settings on the measurement equipment -- there are algorithms such as Ra and Rz for roughness, but those shouldn't be used if your only specification is flatness of 0.1.

WebApr 11, 2024 · Datum Reference Frame. The datum reference frame (DRF) is a GD&T term that refers to the coordinate system that locks the part’s degrees of freedom during inspection and measurement. By ‘locking’, it means that it orients and locates the part in space and provides a base system for all tolerance zones.
