Monitoring and capability of measuring equipment: Important elements to assure product quality and process quality

Measuring equipment used in the factory gets worn by usage just like the production machines. This can happen due to both, natural erosion and non-professional handling. Even if it is not used for a longer time, it is possible that characteristics are changed. However, the measuring equipment has an important influence on the quality of workpieces produced. For this reason it has to be checked periodically by inspection equipment monitoring to assure its utilisability. Measuring equipment is used very often to run statistical process controls; so it is therefore necessary to test its capability to ensure a steady production process
