摘　　要：针对在新产品的开发过程中,由于快速成型设备工作台成型尺寸的限制,对于类似摩托车覆盖件等大型快速成型样件的加工难题。本文分析了快速成型技术和精密雕刻技术在加工过程中的优缺点,提出在摩托车覆盖件的开发过程中,用精雕机和快速成型机结合的方法来进行新产品样件的制作,并且运用基于特征的数据分块技术,对大型样件进行合理的分块,再分别加工后拼合的方法来解决大型快速成型样件无法一次成型的难题,从而加快新产品开发的速度,降低开发成本,实现模型的快速制造。最后以某新型摩托车覆盖件的样件制作为例,阐述了该方法在新产品开发中的具体应用。Because of the small workbench molding size of rapid prototyping equipment,the processing of large rapid prototyping samples is a problem during the new product development process,for example,motorcycle covering.The relative merits of accuracy engraving technique and rapid prototyping technique during processing are discussed.The method combining accuracy engraving machine and rapid prototyping machine to processing new motorcycle cover samples is proposed.And the surface data segmentation technique based on features is adopt to divide the large rapid prototyping sample reasonably,and then the small parts are collaged after respectively processing,so the problem of large rapid prototyping sample cannot once molding is solved.The speed of new product development is accelerated.The cost of new product development is decreased.And the rapid manufacturing is realized.This method has been applied to the processing of new motorcycle cover samples and the application method is expounded.
