Chang Jian

Abstract:This paper presents an algorithm for designing the special drilling jig and tooling for machining the holes of hingetype parts.The algorithm generates the main structure of the drilling jig by recognizing the threedimensional model of the part，obtains the design parameters of the tool according to the geometric relationship and the related process knowledge.The parameters of each component of the drilling jig are solved according to the drilling jig structure and tool parameters.The development of an example test proves that the algorithm is effective and can improve the design efficiency and accuracy of the special drilling jig and tool.
