摘　　要：研究了基于快速原型和金属电弧喷涂(RP-AMS)法快速制造金属模具过程中的精度问题。从理论和实验两方面对模具制造精度有直接影响的光固化原型“抛光误差”进行了定量分析并给出减小抛光误差的补偿方法;以实验为基础,合理利用电弧喷涂法制造模具过程中的收缩特性和微膨胀特性,可以达到较好的综合误差控制效果。The accuracy of a rapid manufacturing process for sheet m etal stamping with RP and AMS (Arc Metal Spray) is presented. Because the “pol ish error” influences the rapid manufacturing process, the “polish error” of SL p rototype is analyzed detailedly through theoretical and experimental approadn. On the base of experiments of expanding characteristic of β-plaster and contrac ting characteristic of AMS process, the control of integrated error for the proc ess of AMS-dies fabrication is studied. The error con...
