基于实体的铸造活塞用金属型CAD系统的研究

Study on Metal Mould CAD for Entity-based Piston Casting

在国外ＣＡＤ／ＣＡＭ软件的基础上，采用基于实体的建模思想，建立了铝硅合金活塞铸造用金属型ＣＡＤ系统，可实现零件的概念设计、实体建模及二维图纸输出。

Abstract Based on foreign CAD/CAM software,using the method of entity-based modeling,a CAD system of metal mould for piston castings has been established,which can accomplish the conception design of parts,entity modeling and 2-D drawing output.
