Surface finish dimension

WebSurface finish involves the process of altering a metal’s surface through reshaping, removing or adding, and is used to measure the overall texture of a surface characterized by: Lay – The direction of the predominant surface pattern (often determined by the manufacturing process). WebRa (average roughness) measures the deviation of a surface from a mean height. The horizontal line through the profile represents the arithmetic mean height. The blue areas represent the deviations from that line. Ra, then, is the …
