摘　　要：为解决空间曲面零件的加工难题,分析空间曲面电火花线切割加工的运动规律,建立电火花线切割极坐标加工系统的数学模型。研制翻转式自动分度数控回转工作台,开发多轴联动线切割加工控制软件,形成空间曲面电火花线切割加工系统。与国产高速走丝电火花线切割机床相结合,加工出理想的空间曲面零件。拓宽了电火花线切割加工的工艺范围,从根本上解决空间曲面零件高速走丝电火花线切割加工的关键技术问题。该方法可广泛应用于模具制造及空间曲面零件加工。For the purpose of developing space surface processing system,the motion laws of WEDM（wire electrical discharge machining） for space surface parts were analyzed,and the mathematical models of pole coordinate WEDM processing system were built.Through developing turnover type automatic graduation numerical control backward table and control software of multi-axis linkage WEDM,a space surface processing system of WEDM was formed.The system was applied to machine ideal space surface parts by united use of domestic high-speed WEDM.The machining capability of WEDM is widened by the system and the key technical problem of high-speed WEDM for space surface parts is resolved.The method can be widely applied to model manufacture and space surface machining.
