本文介绍了用霍普金森杆分离法测量电火花加工过程反作用力的方法。利用该方法，在不受测量系统固有频率影响的情况下，得到了正确的反作用力波形。研究了介质流体和放电位置对反作用力的影响。在测量连续两次脉冲放电所产生的反作用力的基础上，讨论了实际电火花加工过程中作用在工具电极上的反作用力。
This paper describes the measurement of process reaction force generated in EDM using the Split Hopkinson Bar method. Using this method, the correct waveform of the reaction force was obtained without being influenced by the natural frequency of the measuring system. The influences of the dielectric fluid and discharge position on the reaction force were investigated. Based on the measurement of the reaction force caused by two consecutive pulse discharges, the reaction force applied to the tool electrode in the actual EDM process is discussed.
