Evaluation,Revision and Application of the NBS Stylus/Computer System for Surface Roughness Measurement:Minicomputer Software.

摘要

A thorough description of all the software used at NBS for characterizing surface texture is given in this report. The description includes flow diagrams and detailed,annotated listings of machine language programs for step-calibrating the system,for acquiring digitized surface profiles and for calculating from these profiles important parameters and statistical functions. Parameters and functions included are the arithmetic average value,mean square value,average wavelength,average slope,amplitude density function and autocorrelation function.
