The … WebDec 6, 2024 · Surface Roughness. It is amount of deviation in direction of normal vector of real surface from its ideal form. It is represented by (R), or by symbol in some technical documents. Some Roughness parameters:- (As per ISO 4287) Ra – Arithmetic average roughness value. Rz – Mean roughness depth. Rz1max- Maximum roughness depth.
