“…These layouts specify the optimum positions where the fixture should contact the workpiece being machined. Rulebased [Nee & Kumar (1991), Roy et al (1997), Trappey & Liu (1992)] and genetic algorithm [Krishnakumar & Melkote (2000), Wu & Chan (1996)] methods are typical approaches that have been used to develop CAFD systems. However, such systems do not specify the actual physical form the individual units that comprise a fixture should assume.…”

Fixtures accurately locate and secure a part during machining operations. Various computer-aided fixture design (CAFD) methods have been developed to reduce design costs associated with fixturing. One approach uses a case-based reasoning (CBR) method where relevant design experience is retrieved from a design library and adapted to provide a new design solution. Indexing design cases is a critical issue in CBR, and CBR systems can suffer from an inability to distinguish between cases if indexing is inadequate. This paper presents CAFixD, a CAFD methodology that adopts a rigorous approach to defining indexing attributes based upon axiomatic design functional requirement decomposition. A design requirement is decomposed in terms of functional requirements, physical solutions are retrieved and adapted for each individual requirement, and the design is then reconstituted to form a complete fixture design. This paper presents the CAFixD framework and operation, and discusses in detail the indexing mechanisms used.

“…In order to satisfy the requirement of mass customization of the market, the modern enterprise produce a large number of derivative products, therefore, the enterprise has many types or series of products. [1] It is generally believed that similar types of products are with similar composition. And if the type of products is different, but the name of the products, characteristics and machining accuracy requirements are the same, we can consider their technological characteristics as similar, at the same time if the processing surface, clamping characteristics, production batch and equipment conditions are the same, we can consider the structure of the fixture as similar.…”

When turning and grinding the long axis with cone thin-walled, they are clamped to be deformation easily and positioned difficultly. Based on the existing theory of clamping with the conical sleeve, we design a new type of fixture in this paper. The outer cone of the fixture cling to the inner cone of the workpiece, it is sealed hermetically at the both ends. The head of the sleeve stretch out of a cylindrical boss, we can use the three-jaw chuck to position it on the machine tool. Also we use the steady rest to fix the end of the sleeve. The steady rest connect with the shell of a rotary joint. The end of the rotary joint screw with the sleeve, the other end of it is connected with a getter pump. It formatted a vacuum between the sleeve and the workpiece by the use of holes around the circumference of the sleeve. The utility model to the fixture used for thin wall conical parts with long shaft.
