Abstract

In micro manufacturing the advantages of compliant mechanism—e.g. the high precision and the absence of friction—are particularly useful. However, the design process of appropriate compliant mechanisms is a complex task with a wide number of research areas to consider. This article addresses the challenging process of designing compliant mechanisms for feed units in small machine tools. Therefore a comprehensive design methodology for compliant mechanisms is developed and the corresponding tools are analysed. To generate an adequate topology a deeper look into the mechanical characteristics of compliant mechanism is carried out to achieve an efficient model of the mechanism in the final application. Subsequently, a control problem for optimising the trajectory of a prototype feed unit is developed and implemented. Based on these findings a comprehensive design methodology of new feed units with compliant mechanism is proposed. This methodology is applied to prototypes of feed units and the results are shown. Eventually, the manufactured feed unit is integrated in a small machine tool that is assembled of other modules which were developed within the research program.
