摘　　要：通过对Pro/ENGINEER的研究,借助其开发工具Pro/TOOLKIT实现了对CAD模型直接切层.切层所得零件剖面图形可直接用于面曝光快速成形系统.该方法与传统的对STL模型文件切层方法相比方便快捷,并且减少了模型表面化引起的零件误差,从而使截面轮廓精度更高.该方法为面曝光快速成形系统快速制作高精度零件提供了基础.Slicing is one most important steps of Mask Projection Stereo-lithography techniqing. After researched Pro/ENGINEER, it is achieved by slicing functions for CAD models using development tool Pro/TOOLKIT. Cross sections of parts gained from slicing can be used in Mask Projection Stereo-lithography system. This method is conveniencer and faster than traditional method of slicing based on STL format, and reduces the accuracy error caused by model apparent, thus, the outline precision of cross section is higher. The experiment result indicates that the direct slicing method provides a foundation for Mask Projection Stereo-lithography system manufactureing high accuracy parts.
