Post Processing of Roughness Raw Data

Article Preview

Abstract:

This paper deals with the system of roughness measurement, especially with the problem of data filtering and processing the results. Theoretical part describes shortly terms roughness, waviness and shape as surface integrity parameters. During phase of measuring we obtain all these three constituents in common. The most important task of post processing is separation of them. That is possible due to roughness HW and SW filters. Other parts of this paper contain SW data filtering description and philosophy of HW filtering. Last part of this article describes SW filters with basic mathematical apparatus, areas of usage and limitations.
