| Summary: | Good machining performance and high surface quality can be achieved in engineering compound materials when subjected to ultrasonic vibration machining systems. This study established an ultrasonic vibration system with a complex disk tool. The finite element simulation model of the complex disk tool was created using ANSYS software. Modal analysis was utilized to obtain the disk’s resonance frequency and other parameters. Based on the local resonance characteristics of the system and the simulation results, the horn, transducers, and other components were designed. The node position of the compound ultrasound system can be accurately determined, leading to the acquisition of a cutting disc with a disc-shaped cutting edge that exhibits equal center distance and amplitude longitudinal vibration in the ultrasonic vibration system. This vibration system conforms to the local resonance theory of slender rods. A theoretical method for calculating the nodes of the ultrasonic vibration system with a discoid non-resonant frequency was developed. A slight deviation between the measured resonance frequency of the system and the theoretical results was observed. Thus, a reliable design method for ultrasonic vibration cutting systems with complex disk tools has been provided. |
