【摘要】 分析了电火花放电加工间隙控制系统功能需求,进行了模块化总体结构的设计。为了实现自动控制功能,在传统的参考电压比较法间隙状态控制系统中增加了参考电压调整模块,构成一个闭环间隙控制系统。根据加工效率的计算结果来自动优化初设的门槛电压值的设计思路,可以提高控制间隙状态的精度和效率。更多还原

【Abstract】 The EDM gap control system functional requirements were analyzed in this paper,and the overall structure of modular was designed.In order to achieve automatic control functions,the article in the gap state of comparative of reference voltage adjustment module in the control system,constitute a closed-loop clearance control system.Automatically optimize the initial threshold voltage value of the idea,which can improve the accuracy and efficiency of the control gap state according to the calculation results of the processing efficiency.更多还原
