Final answer:
Ultrasonic cleaning is the process that uses sound waves and imploding bubbles to clean objects by creating cavitation within the cleaning fluid, releasing energy that cleans even the smallest of crevices.
Step-by-step explanation:
The mechanical action in the automated cleaning process that uses sound waves and imploding bubbles is called ultrasonic cleaning. This process involves the use of ultrasonic cleaners, which utilize frequencies typically around 20-40 kHz to clean various items such as jewelry, lenses, dental and surgical instruments, and industrial parts. The main cleaning mechanism in ultrasonic cleaners involves the generation of ultrasonic waves in a fluid, leading to cavitation.
This cavitation results in the formation and implosion of millions of microscopic bubbles, releasing energy that contributes to the cleaning action. This energy is capable of accessing small crevices and removing contaminants due to the shock pressures produced by the imploding bubbles.
