On a Statistical Method of Taking Roughness and Waviness out of Profile Curves of Shaper Worked Surfaces

Abstract

It is generally known that profile curves contain roughness and waviness. But both the definition and the method of distinction have not been clearly shown yet. In this report, therefore, shaper worked surfaces have been prepared to be analized statistically by applying the theory of runs, the mean successive difference, the moving averages and average length and variance curves.
As the conclusions, the roughness and waviness have been distinguished statstically, clearly and objectively. And the evaluations of roughness and waviness have been examined by applying the new methods statistically.
