Abstract: In this paper a theoretical model of grinding force in Ultra-high speed grinding (UHSG) is deduced. Considering the strength decreasing and softening of workpiece material after it is heated, the theoretical formulae for calculating grinding force are established. Qualitative analysis is proceeded on the proportion coefficient changing with the increase of grinding speed. At last, some simulative calculations are proceeded according to grinding temperature model and some useful conclusions are obtained.
