Outline of Final Research Achievements

Japanese manufacturing industry is strongly requested to produce products with sufficient functions in a reasonable price for new customers in emerging markets. For manufacturing such products, evaluation of their producibility in early design stage is indispensable, otherwise problems are detected in the late manufacturing preparation stages and costly re-works become necessary. We found that most of the constraints relating to the producibility can be evaluated in a uniformed manner by placing simple geometric objects such as spheres, cylinders and cones in the internal side or external side of the geometric model of the products. In this research work, we developed new parallel algorithms for evaluating the producibility based on the concept mentioned above. We also developed parallel processing software systems using graphics processing unit (GPU). Developed software is provided to some leading manufactures in Japan for evaluating their functions with real products.
