摘　　要：针对国内外现有的金属直接快速制造技术中存在的制件表面质量不高的瓶颈问题,开发了在制造过程中将等离子熔积增材成形与铣削光整减材复合的金属零件直接快速制造方法。研究该复合制造工艺参数对熔积成形性和形状特性以及热态干铣削刀具和工艺的影响规律,找到合理的工艺条件并用其试制出金属零件原型,为改善快速原型表面质量提供了有效的途径。For solving the bottleneck problem of low surface quality in existing direct rapid metal prototyping technologies at home and abroad, a direct rapid metal prototyping method by hybrid additive plasma deposition shaping and removable surface milling finish technologies was developed in this paper. By researching the effects of hybrid fabrication processing parameters on deposition formability, shaping features, thermal dry milling tools and the process, suitable processing parameters are found out and metal parts are then trial-manufactured,thereby an effective approach is provided to improve the inside and outside qualities of rapid metal prototype.
