In this paper, a methodology to perform fixture design as an integrate
d aspect of process planning is proposed. A three-phase methodology fo
r the fixture design activity has been developed. The three phases inc
lude predesign analysis (phase I), functional analysis (phase II), and
productivity improvement (phase III). In phase I, the product design
information is studied, and initial fixture design aspects are develop
ed. In phase II, the clamping and location aspects of fixture design a
re addressed for the given initial process sequence and product design
information. Phase III involves studying ways to increase the product
ivity including using simultaneous machining approaches, multiclusteri
ng, use of specialized jigs, etc.
