Abstract: The theories and application of modular fixture design automation are investigated. Under the guidance of the theory of generalized mapping, a “top–down” fixture design automation software is developed. On the analysis of the fixturing characteristics of workpiece, the design requirement is extracted. The process of function-form mapping relationship is researched, whereby the conceptual fixture structure is deduced. The muti-schematic reconstitution of the conceptual fixture structure is realized. And the theory and methodology is lastly exemplified, where a new approach of fixture design automation is explored.
