Each individual abrasive grain on a grinding wheel acts as a cutting tool. As the grinding wheel applies forces to remove material, the workpiece applies resistance forces to the wheel. When using vitrified or metal-bonded grinding wheels, these resistance forces lead to fracturing of the abrasive grain from the bond.
SGE serves as a measure of efficiency of the grinding process and is calculated from the grinding power by the following equation: Specific Grinding Energy (SGE) = (Grinding Power) ÷ (Material Removal Rate) The symbol for SGE is U' and the units of specific energy are Btu/in 3 and J/mm 3. As shown in the equation above, …
