A water jet machining is an industrial tool capable of cutting a wide variety of materials using a very high-pressure jet of water, or a mixture of water and an abrasive substance. This paper addresses the concept of the Intelligent knowledge base system (IKBS) for optimization of product design and manufacturing process for water jet machining in computer based concurrent engineering environment. The I KBS links with feature library. The design specification is acquired through a feature based approach. The IKBS links with material data base which holds attributes of more than ۲۰ type of materials. It also links with abrasive data base which hold attributes of ۸ types of abrasive, and also ۴ type and size of machine. IKBS is also links with machine data base which hold machine parameters. For each design feature, IKBS provides information needed for design and manufacturing optimization. The IKBS can be used as an advisory system for designers and manufacturing engineers. It can be used as a teaching program for new water jet operators in computer based concurrent engineering environment.
