What is Surface Finish and Surface Roughness? - ExtruDesign

The finish symbol reveals how to finish a weld. For example the following letters are used to convey this information on a symbol: C = chipping M = Machining G = Grinding For example there is a G, as shown below, so the welder needs to grind the weld to create the contour that is needed, and the actual contour is to be 'flush'.

Surface grinding - Wikipedia

Surface grinding is the most common of the grinding operations. It is a finishing process that uses a rotating abrasive wheel to smooth the flat surface of metallic or nonmetallic materials to give them a more refined look by removing the oxide layer and impurities on work piece surfaces. This will also attain a desired surface for a functional ...

Surface Roughness Conversion Chart Tables- Engineers Edge

For tolerancing the geometry (sharpness) of edges (within cross-sections) a separate standard ISO 13 715 has been developed. Edges are intersections of two surfaces. Edges always exhibit deviations from the ideal geometrical shape (burr or undercut or passing) (Fig. 22.1). The size of these ...
