Simulation and Experiment on Dynamic Characteristics of Wire Electrode in WEDM

In wire electro discharge machining with low wire travelling speed(WEDM LS) the effects of wire vibration on machining state and process are investigated.By means of computer simulation,the mode of wire vibration as well as its influence on shift and distribution of discharge points have been analyzed.The results show that technological parameters such as pulse duration,pulse interval,working current and wire tension can evidently affect the shift and the distribution of discharge points so that the best discharge distribution and state will be obtained by selecting appropriate technological parameters.This study provides a relevant theoretical basis for improving machining stability of WEDM LS and preventing wire electrode from breakage.
