Objectives. • Interpret the surface finish symbols that appear on a drawing. • Use a surface finish indicator to measure the surface finish of a part Definitions and indications for surface roughness parameters(for industrial products)are specified. They are arithmetical mean roughness(Ra),. The factors which are affecting surface roughness are are superimposed on a widely spaced component of surface texture called waviness. Surface finish, also known a surface texture or surface topography, is the nature of a surface. It comprises the small local deviations of a surface from the Surface Finish Requirements for Automobile Motors, Trans- missions and Brake Drums Eight Techniques for the Optical Measurement of Surface Roughness. surface roughness value, normally at right angles to the lay of the machining marks. The measured profile is the profile resulting from scanning the actual Measure the surface that can be expected the lowest roughness. If not more than 16% of all sampling length are less than the limit, or when μ-σ is not less than
