shearing force in grinding process
What are shear forces and how do they affect your bioprocess?
12.10.2021Shear stress is developed due to the presence of velocity gradients within the fluid flow. In other words, slower fluid flow will reduce the speed of an adjacent layer of fluid in the same flow, whilst a faster layer of flow will have an accelerating effect on the slower layer.

Grinding Process
In the case of some grinding, honing, and free abrasive grinding operations with bonded grains, cutting edge engagement is also force bound. It is hereby often the case that the grain remains relatively fixed and penetrates into the workpiece at a predetermined path by the relative movement between the tool and the workpiece (Fig. 3 ).

Metal Cutting: Meaning, History and Principles
Shearing takes place along a shear zone (shear plane). The shear plane is actuality a narrow zone. It extends from the cutting edge of the tool to the surface of the work piece. This plane is at an angle called the shear angle (φ), with the surface of the work piece. Shear zone has a major influence on the quality of the machined surface.
