摘　　要：对原型的精确重构和基于原型的再设计是反求工程的应用目标之一。在制造业中,由于制造误差、测量误差、三维拟合精度等多种因素,使得依据实物原型重构而形成的制造数据与原型参数有较大的差距,在某种情况下,反求出的产品将会失去使用性能。针对此问题,提出了反求工程中存在有实物原型参数、重构参数和原始设计参数的参数体系,阐述了在不同的场合根据不同的要求应求出不同的参数,并提出了应用在制造业中的反求工程应逆求出制造实物原型所依据的原始设计参数,并依此作为制造新产品的依据。分析结果对强化反求工程在制造业的应用、突出反求工程的"创新"功能具有重要意义。Accurate reconstruction of prototype and redesign based on prototype is one of the application goals of reverse engineering. In manufacture industry,because of many kinds of facts,such as,manufacturing errors,measuring errors and three-dimensional fitting precision,and so on,there was obvious gap between prototype parameter and manufacturing data that was formed based on objective prototype reconstruction,in some cases,the product to be reversed lost its using performance. Aimed at this problem,it puts forward that there is a parameter system that includes the objective prototype parameters,reconstruction parameters and original design parameters in the reverse engineering,and expounds that the different parameters must be obtained according to the different demands in a different situation. It proposed that the reverse engineering used in manufacture industry should find reversely the original design parameters that are foundation of making objective prototype,and should use it as the basis of making new products. The analysis result has great significance to strengthen the application of reverse engineering in the manufacturing industry,and highlight the＂innovation＂function of reverse engineering.
