摘要
【目的】满足高硬材料的加工需求,解决高硬材料难以加工、效率低下、刀具损耗率高的问题。【方法】课题组基于旋转超声加工和电解加工提出了旋转超声加工辅助电解加工的方法,不仅分析了加工原理,选择了加工参数,还优化设计了加工系统,对换能器和变幅杆综合材料、密度、频率、纵波声速等因素进行了具体参数设计。【结果】对高速钢进行了不同加工方式的电解平面加工试验,发现同等条件下,机械磨削加工的圆孔明显比另外两种加工方式加工的圆孔粗糙,而旋转超声辅助电解加工的圆孔不仅直径大,而且表面更加平滑。【结论】机械磨削的效率比另外两种加工方式低,旋转超声辅助电解加工的加工深度最好,材料去除率更高,得到的加工表面也更加平滑,对高硬材料的加工效果更好。
[Objective]To meet the processing needs of high hard materials and solve the problems of difficult processing,low efficiency,and high tool wear rate of high hard materials.[Method]The research group proposed a method of rotating ultrasonic machining assisted electrochemical machining based on rotating ultrasonic machining and electrochemical machining.It not only analyzed the machining principle,selected machining parameters,but also optimized the design of the machining system.Specific parameter designs were carried out for factors such as material,density,frequency,longitudinal wave sound velocity,etc.of the transducer and amplitude transformer.[Result]Electrochemical planar machining experiments were conducted on high-speed steel using different processing methods,and it was found that under the same conditions,the circular holes processed by mechanical grinding were significantly rougher than those processed by the other two processing methods.The circular holes processed by rotary ultrasonic assisted electrochemical machining not only had larger diameters but also smoother surfaces.[Conclusion]The efficiency of mechanical grinding is lower than the other two processing methods.Rotary ultrasonic assisted electrochemical machining has the best processing depth,higher material removal rate,smoother processing surface,and better processing effect on high hard materials.
