Shear Blade - Cutting Edge Grinding
Shearing is a metal fabricating process. A typical shearing machine will use both an upper and a lower guillotine shear blade which are offset from each other by a small, predetermined amount. Shearing is used for straight cuts of flat metal stock. Shearing is characterized by its ability to cut a range of lengths quickly and efficiently.
Sheet Metal Cutting (Shearing) - CustomPart.Net
Punching is a cutting process in which material is removed from a piece of sheet metal by applying a great enough shearing force.Punching is very similar to blanking except that the removed material, called the slug, is scrap and leaves behind the desired internal feature in the sheet, such as a hole or slot.

•Higher shear plane angle means smaller shear plane which means lower shear force •Result: lower cutting forces, power, temperature, all of which mean easier machining Figure 21.12 -Effect of shear plane angle : (a) higher with a resulting lower shear plane area; (b) smaller with a corresponding larger shear plane area.
High-shear mixer - Wikipedia
High-shear powder induction systems also offer easy interchangeability with multiple tanks. High-shear granulators. A high-shear granulator is a process array consisting of an inline or batch high-shear mixer and a fluid-bed dryer. In a granulation process, only the solid component of the mixture is required.
