Stability of roundness measurement system

In order to improve measurement capabilities and to ensure good foundation for further research in the field of roundness measurements National laboratory for length has implemented several modifications on a commercially available roundness measurement device Mahr MMQ3. Furthermore, dedicated measurement software which includes all modern algorithms for out of roundness error calculation has been developed. These improvements to the measurement system provide a new possibility to perform a large number of consecutive measurements over extended time period. Result of those measurements provides insight into temperature and mechanical stability of the measurement system. Mechanical stability and temperature influence by the means of temperature drift are discussed.
