Grinding Force - an overview | ScienceDirect Topics

The grinding force obtained during the conventional grinding process was found to vary less than that obtained using laser-assisted grinding. 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.

Forces acting on saw teeth during timber processing – a ...

According to our working hypothesis, the four types of forces acting in the saw-teeth during timber processing are (1) the sawing or cutting force F s, (2) the saw dust acceleration force F a, (3) the saw dust compacting force in the gullets F c, and (4) the force needed to overcome the increasing friction from wear F w.

Force system in orthogonal cutting

small proportion of the cutting force at large values of the undeformed chip thickness h c. At the small values of h c, however, the force that acts on the tool edge is proportionately large and cannot be neglected. Because of high stresses acting near the cutting edge, deformation of the tool material may occur in this region.
