高频窄脉冲电化学加工间隙的在线检测与控制

High frequency short pulse electrochemical machining(HSPECM) characterized by higher machining precision and better machining stabilization can process workpiece in smaller dimensions.

高频窄脉冲电化学加工具有加工精度高、稳定性好等优点,可以加工出微小尺寸的工件。

This paper introduces the basic principle of higher frequency group-pulse electrochemical machining(HGPECM), analyzing emphatically the circuit detecting project and the short circuit protect measure in the machining process, and subsequently recommends the design of the circuit.

主要介绍了高频群脉冲电化学加工的基本原理,重点分析了加工过程中电流检测及短路保护措施及电路设计方案,其次介绍了待检测的电流信号形式及电子功率器件——绝缘栅双极型晶体管(Insulated-GateBipolarTransistor,IGBT)。
