摘　　要：为了提高电解加工过程的数字化程度与控制精度,本文采用PLC、仿真模型、数据库、Unity3D多平台相结合的方式构建加工过程数字孪生系统,利用PLC和仿真模型结合PD控制算法的方式,对刀具进给速度实时调节,实现加工电流的稳定输出,通过Unity3D平台完成整个加工系统的可视化控制系统设计,结合电解加工实验对系统性能进行了评价。实验结果表明:文中方法能够实时收集电解加工过程中的电流、电压、温度、压力等关键数据,实现了数字化仿真、预测以及控制功能;提高了加工电流的稳定性,可以更快的到达加工电流目标值,同时超调值和系统震荡幅度也更小,从而改善了杂散腐蚀现象。In order to improve digitization and control accuracy in the electrolytic machining process,this paper presents a digital twin system based on the combination of PLC,simulation model,database and Unity3D multi platform.PLC and simulation model are combined with the PD control algorithm to regulate the real time adjustment of the tool feed rate,realizing the stable output of machining current.The visualization control system of the machining system is designed by using the Unity3D platform,and its performance is evaluated in a electrolytic machining test.The experimental results show that the method proposed in this paper can collect real time current,voltage,temperature,pressure and other key data in the electrolytic machining process,realizing digital simulation,prediction and control functions.The stability of the machining current is improved,which makes the target value of the machining current be reached faster.And also the smaller overshooting value and the amplitude of the system oscillation greatly retard the stray corrosion.
