The current work focus on the issues related to the consideration and application of manufacturing knowledge and manufacturing data during product design through integrated product and process design. The work in this direction is expected to enhance productivity and quality and reduce total cost and the time to market. The paper presents a long term research work that involves development of a computer assisted system for the manufacturability evaluation of a given prismatic part. Feature technology and computer assisted tools for automation have been employed for the utilization of manufacturing knowledge and information about the available manufacturing recourses during the design of the product. The features of the system developed for this purpose is described in this paper.
