Abstract
The experiment apparatus of ultrasonic vibration-assisted microabrasive waterjet polishing is developed. The simulation model of ultrasonic nozzle is analyzed with the help of ANSYS software. The simulation result shows that the ultrasonic vibration leads to a good result that the maximum frequency with the value of 20908 Hz is obtained at the outlet of ultrasonic nozzle, and the vibration type is axial mode. Then the vibration frequency and amplitude of the developed experiment apparatus are tested using the ultrasonic transducer impedance analyzer and the laser displacement sensor. The measured result indicates that the vibration frequency is 19099 Hz and the amplitude is 22 μm, which means the experiment apparatus is well developed and satisfies the work requirements. The verifying experimental result shows that the ultrasonic vibration helps to enhance the machining ability of the abrasive waterjet, and the removal material volume and erosion depth are increased obviously.
Highlights
As one of the fastest growing nonconventional machining processes, abrasive waterjet (AWJ) plays an important role in many manufacturing applications such as cutting [1], surface cleaning [2], and surface treatment [3]
The vibration could be produced by a vibrator made of a giant magnetostrictive material, and it belongs to mechanical vibration [4, 5]
Another type of ultrasonic vibration produced by the ultrasonic vibrator is used to assist the diamond wheel and improve machining efficiency and precision [6]. ere is no doubt that in these research studies, the vibration brings good effect on polishing results, but this conventional grinding tool inevitably results in severe thermal damage to workpiece [7, 8]
