Preventive Quality Assurance in the Context of Micromechanical Component Fabrication by Microfeatures

This article presents an approach of the Microfeature Catalog as an information database that is structured by features and that operates as the basis for preventive and nonpreventive quality assurance information. The microfeature concept is adapted and evaluated in the specific environment of the fabrication of micromechanical components. The development of microparts demands the further development of the new manufacturing technologies, as well as an appropriated development of the accompanying processes like quality assurance. A closed information loop between design, manufacturing, and quality assurance is realized.

Keywords:

• Interactive quality assurance system
• Preventive process-oriented quality assurance
• Microfeatures
