摘　　要：结合工作实践对逆向工程的研究和应用现状进行了总结,针对逆向工程模型可重用性的不足,提出了一种实物反求工作流程的改进方案.对在通用CAD/CAM系统中进行可重用模型构建的实现技术特征库和知识库的建立、基于特征的点云分割、特征及特征树的建立及应用进行了研究.Recent situation of research and application of reverse engineering was summarized in terms of engineering practice. Facing the insufficient reusability of the model in reverse engineering, a modified project of work flow of object＇s inverse processing was presented. Technique of constituting reusable model in available CAD/CAM system, namely the establishment of library of features and knowledges, splitting of point-cloud based on features, constructing of features and feature tree was investigated.
