shearing force in grinding process

Grinding Force - an overview | ScienceDirect Topics

The grinding force for laser-assisted grinding without an air coolant was very close to the conventional machining process, especially at the end of the grinding process. The largest grinding force was found when the laser was used with an air coolant with the grinding force varying greatly along the machining distance. This was because when ...
