WebUnderstanding Surface Roughness. Surface roughness is one component of describing how the shape of a surface deviates from its ideal form, where higher values correspond to rougher surfaces while lower values indicate the surface is smooth. Roughness describes high spatial frequency errors, meaning very small deviations on the order of ... WebFeb 27, 2024 · Surface Finish. Surface finish measures small-scale irregularities on a surface, usually due to the polishing process. Rough surfaces aren’t as durable as smooth surfaces and may not be ideal for some applications, Power. Power is a surface accuracy specification for curved surfaces (surfaces that have power).
