On the mechanics of the grinding process Part I

01/12/2003 Grinding, in general, is a very complex material removal operation involving cutting as well as plowing and rubbing between the abrasive grains and the workmaterial,.

The primary objective in FFG is to obtain the required form, finish, and accuracy while the

5 Facts About Grinding Processes Monroe Engineering

Grinding is machining process that’s used to remove material from a workpiece via a grinding wheel. As the grinding wheel turns, it cuts material off the workpiece while creating a smooth surface texture in the process. While grinding sounds simple enough, there are probably some things you don’t know about this machining process. Below are five interesting facts about grinding.
