摘　　要：针对激光快速成形的钛合金产品会出现"鱼鳞状"波纹表面、一般机械加工手段不易去除的难题,析钛合金材料特性和激光快速成形的原理及过程,总结激光快速成形典型零件支撑框生产过程中的加工经验,采取了针对艺措施及合理的工艺流程,并结合材料特性选用了合理的加工方法。通过对慢走丝线切割等精密加工技术的研究和应用,解决了去除激光快速成形产品"鱼鳞状"波纹表面的难题。。The paper is aimed at the poser that the general technical process and machining methods can’t remove the fish scale-shaped corrugated surface of the titanium alloy products generated by laser rapid prototyping easily. By analyzing the material characters of titanium alloy together with the principles and process of laser rapid prototyping, the paper summarizes the process experience of the procedure of typical component that supporting-frame is generated by laser rapid prototyping. And the paper adopts individualized processing measures and reasonable processing flows,chooses reasonable machining methods with material characters. Through the research and appliance of the slow-feeding wire-cutting and other manufacturing technology, the paper resolves the poser to remove the fish scale-shaped corrugated surface of the titanium alloy products generated by laser rapid prototyping.
