The surface finish of a machine part may be important to reduce friction with other machine parts or to improve the aesthetics of the part. Surface finish measurements (RMS, Ra, etc.) describe the microscopic deviations of a surface from a perfectly smooth ideal plane. Note that surface finish is a different parameter than a machine part’s ...
