Macro-topography effects on dry grinding with CBN wheels

International Journal of Mechatronics and Manufacturing Systems (IJMMS), Vol. 1, No. 4, 2008

Abstract: Grinding involves high specific energy compared to other machining processes due to the negative rake angle of grains. Almost all this energy is converted to friction, generated high heat, which can have harmful effects on workpiece surface quality specially in case of dry grinding. Based on the optimisation of chip formation process, using a new concept of special structuring by special dressing of the vitrified grinding wheels, the heat generation is reduced. The results show a significant reduction of grinding forces in the new method compared to the conventional one at the same material removal rate without burning or thermal damages on the surface of workpiece.
