Quality assurance in micro production

Abstract

Quality assurance is essential for an efficient support of all developing and manufacturing processes and activities with the forefront objective to reach robust processes with a high throughput of parts meeting their functional requirements. Due to the lack of a broad base of experiences regarding the still developing manufacturing technologies in micro production an adequate quality assurance plays an even more important role in order to efficiently support the transition of micro production processes from non-robust to stable processes. Thereby, quality assurance faces particular challenges in micro production, which render a reasonable application of common quality methods difficult or even impossible. Consequently, it is essential to develop new concepts or adjust widely applied quality assurance methods in order to support and continuously improve the development- and manufacturing processes in micro production. Within the scope of the Collaborative Research Center (SFB) 499 “Design, production and quality assurance of primary shaped micro components manufactured in ceramic and metallic materials” the approach of the subproject working on the topic quality assurance is threefold: (i) An efficient and process-accompanying information management has been implemented and will be enhanced further on. (ii) Specifically adjusted preventive methods of quality assurance have been developed and applied. (iii) In order to implement an efficient operational quality assurance performance data of the manufacturing processes has been collected and provided. In the future this supply of data will be used to control and improve the manufacturing processes.
