Abstract Because the traditional fixture design can not meet the needs of enterprises and the market, the traditional fixture design theory and advanced computer technology combined to develop the CAFD system has become a fixture of new design method. Computer aided fixture design is the computer technology, database technology, parametric design technology in the application of special fixture design. This paper introduces computer aided fixture design and development course, present situation and prospect, put forward computer aided special drilling fixture design of the overall scheme of the system, introduces some key technology, research of interactive technology, case based reasoning in fixture design. Based on the parametric technology and database technology, and studies how to establish the library of standard parts, non-standard parts library and fixture library. In addition, also introduced the location error of the jig and calculation method for stability. According to the theory and thought based on the platform of SolidEdge, using VB6.0, SQL Server2008 database development computer aided special drilling fixture design system, preliminary verification of the related problem.
