摘　　要：为提高电解加工自动化程度、更好地研究工件成形过程,在全面研究电解加工成形规律的基础上,结合UG软件平台开发了电解加工计算机辅助工件成形过程仿真与预测的软件系统。介绍系统的基本结构和组成,对加工间隙内实际电场分布进行分析,进而模拟出工件型面的形成过程。通过对某发动机叶片的工艺试验,验证了系统仿真预测的结果,试验结果表明开发的系统具有较高求解精度,对提高电解加工精度、实现电解加工自动化具有重要意义。The shaping process simulation and final shape prediction are important issues in Electrochemical Machining（ECM）. To improve the automation of ECM, based on the ECM shaping theories, the system of simulation and prediction workpiece＇s shape is developed using UG software. The structure and composition is introduced firstly, and the shape evolution is simulated by analyzing the electric field distribution in the inter-electrode gap. Experiments on machining a blade were conducted and experimental results showed a close agreement with the ones in the system. The system Will do help to improve ECM precision and realize automation of ECM process control.
