In the light of growing global competition, organizations around the world today areconstantly under pressure to produce high-quality products at an economical price. The integrationof design and manufacturing activities into one common engineering effort has been recognized as akey strategy for survival and growth. Design for manufacturability (DFM) is an approach to designthat fosters the simultaneous involvement of product design and process design. Theimplementation of the DFM approach requires the collaboration of both the design andmanufacturing functions within an organization. At present, For some reasons DFM approach isineffectively including lack of interdisciplinary expertise of designers; inflexibility in organizationalstructure, which hinders interaction between design and manufacturing functions. Design formanufacture is the practice of designing products with manufacturing in mind. Early considerationof manufacturing issues can shorten product development cycle time, minimi overall developmentcost and ensure a smooth transition into production. In this paper, part manufacturability underConcurrent Engineering (CE) environment was analyzed in detail. An evaluation system of DFMwas proposed according to CE ideas. A fuzzy set-based manufacturability evaluation algorithm isformulated to generate relative manufacturability indices to provide product designers with a betterunderstanding of the relative ease or difficulty of machining the features in their designs. Ananalytic hierarchy process (AHP) method is introduced to assign weighting factors to features toreflect their functional importance. Results from the case studies show the method available andpracticable
