A surface metrology procedure was established to model the shape of surface height distributions from different manufacturing processes. Many engineering surfaces cannot be represented by a Gaussian distribution. The Johnson translatory system, which consists of three transformations of a Gaussian distribution, was used to classify the surface texture. A computer code to fit the Johnson translatory system by first four moments was developed. The application of the Johnson translatory system to the surface profiles from a variety of engineering surfaces was accomplished. Advantages of this approach include no limitations in describing the shape of surface height distributions and ease of application as compared to current approaches.
