Measurement uncertainty of surface roughness measurement

There are several measurement methods to microgeometric examination of the surfaces machined by different cutting processes. At Department of Manufacturing Technology, Institute of Materials and Manufacturing Sciences, Óbuda University it has a traditional contact (stylus) instrument with related software which is widely used in the industrial practice. All measurements such as the surface roughness are characterized by uncertainties which are essential for accurate measurement of the result since the surface quality is characterized by the obtained roughness measurements. The measurement and the characterization of surface roughness and the method of determining measurement uncertainty are standardized. This article describes the determination and analysis of measurement uncertainty for 2D roughness parameters on surfaces prepared with different cutting methods.
