STATISTICAL TESTING OF THE MEASUREMENT ACCURACY OF MOBILE ROUGHNESS MEASURING INSTRUMENTS

K. Stepien
Abstract:
Surface roughness is a very important factor influencing overall quality of products of modern industry. There are numerous methods of measurements of surface roughness. A very important group of roughness measurements instruments are mobile ones. They are particularly useful in measurements under industrial conditions. However, precision and accuracy of results obtained with the use of mobile instruments can depend on an operator. Therefore, the question is how accurate are measurements carried out with mobile instruments. The paper describes problems relating to measurements of roughness with mobile instruments. It also presents results of statistical testing of the precision and accuracy of a typical portable instrument.
