White Light Interferometer for the Production Measurement Technology From the Research into the Application

Production measurement technology is an important tool of quality control of mechanic work pieces. It is the goal of production measurement technology to ensure comparable measurement results for the evaluation of geometric specifications. The establishment of common standards is a necessary condition to achieve this goal. This paper discusses the requirements for white-light interferometers for a successful deployment in production measurements as well as the necessary measures to derive a defined measurement uncertainty for specific measurement quantities, which are important for quality control. The measurement system capability index C-gk defines if the measurement device is capable to gauge the tolerances of a work piece reliably.
