Jul 03, 2021 Principles of Grinding. In all forms of grinding, three different interactions occur between the abrasive and the machined material. Cutting occurs where the abrasive grain is sufficiently exposed to penetrate the workpiece material and curl a chip, and sufficient clearance exists between the grain, bond and workpiece to flush the chip with coolant or throw it away by wheel action.
Grinding machines, like broaching machines, operate over a range of speeds depending on the type of machine being used.These range from approximately 1250 to 2000m min 1, although in high-speed grinding speeds of up to 5400mmin are achievable Schey, 1987.The two most common grinding applications are cylindrical grinding and surface grinding.

A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.
