It is proposed that the gate valve CAD/CAM system should have the functions of optimum design,finite element analysis, parameterized design, autodrawing and computer aided manufacturing,thereby a gate valve CAD/CAM system is developed.

• 提出闸门CAD/CAM系统应具有优化设计、有限元分析、参数设计、自动绘图和计算机辅助制造等功能，由此开发设计了闸阀CAD/CAM系统。
