虚拟制造可以为各种复杂机械产品提供省时、省力、省钱的最佳方案,是属于国家高新技术研究发展规划纲要新概念、新构思探索的课题范畴,世界各国有关专家都在这方面倾注了相当大的精力。作者因在机械产品虚拟制造方面的瓶颈——几何反算技术方面做了些工作,曾先后受到有关国际会议特邀作报告的来函,多次 Virtual manufacturing can save time, effort and money for all kinds of complex mechanical products. It belongs to the topics of new concept and new ideas explored by the National High-tech Research and Development Program. All the experts from all over the world devote themselves to this aspect A considerable amount of energy. The author has done some work on the bottleneck of virtual manufacturing of mechanical products - the geometric backscattering technique. He has received many letters of special invitation from international conferences,
