Abstract: [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.
