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.
