Energy and temperature analysis in grinding
energy. Specific energy is a measure of process efficiency. It relates to the difficulty of machining a workpiece material. It also relates to wheel wear. For example, where the grinding power is 25 watts per cubic millimetre of material removed per second for a particular workpiece material, the specific energy is 25 J/mm3.
