The Development of Physical Signal Measurement and Control in the Processing of Ultrasonic Machining
Ultrasonic machining (USM) is a mechanical material removal process used to erode holes and cavities in hard or brittle work pieces by using shaped tools, high-frequency mechanical motion, and an abrasive slurry. There are many physical signals in the ultrasonic machining which are related with the material removal rate, machining accuracy, and surface finish. So how to measure and control these signals with accuracy is very important. The aim of the paper is to summarize different kinds of physical signals and the methods of measuring and controlling them in ultrasonic machining.
