摘　　要：通过一系列的实验得出脉冲宽度或脉冲间隔与加工表面粗糙度、精度、机床型号的关系,总结出放电电路能量及电流脉冲宽度、脉冲间隔对线切割电火花精加工表面粗糙度的影响规律。在实际生产加工中,结合实际清况,选择合适的脉冲宽度、脉冲间隔比,调节出合适的加工速度,这样能有效地控制工件的表面粗糙度,提高加工效率。实验结论可为提高线切割加工质量找出一条新途径,也为今后高频电源的开发,加工技术的提高提供重要参考依据。Through a series of experiment pulse width and pulse interval and machining surface roughness,the precision and the machine type of relationship,sums up the discharge circuit energy and current pulse width,pulse interval to wire-cutting electrical discharge machining surface roughness influence law.In the actual production and processing,based on the actual qing regime,choose the right pulse width,pulse width ratio,adjust the proper processing speed,this can effectively control the surface roughness of the workpiece and the improvement of the machining efficiency.The experiment conclusions can improve the wire-cutting quality to find out a new way,but also provide important reference for future high frequency power supply development and processing technology improvement.
