Chapter 5: Grinding Mechanisms Engineering360

A number of diverse methods can be used for gathering evidence to identify the mechanisms of abrasive-workpiece interactions. One possibility is to examine the grinding debris (swarf) produced by the process in order to theorize how it could have been produced. For this purpose, the scanning electron microscope (SEM) is an invaluable tool.
