Abstract
Engineering support system for mechanical design based on the technology of Web Services is proposed and implemented as an integrated design system by CAD/CAM/CAE in distributed environment. Knowledge base system for mechanical design and numerical analysis can help to organize digital processes for design by analysis. Unified information of figure or analysis and processing data by XML expression can be used in each design process under physical restrictions. Web Services can provide high end computing system for the engineering environment for more mechanical engineer and show the possibility of integrated model and experimental system as a basic system of production knowledge.
