Abstract: The orthogonal cutting model of single grain and constitutive equation of glass metal are established, and the micro grinding temperature field of bulk metallic glass is simulated using the finite element simulation system. The grinding temperature of bulk metallic glass and the temperature change trend in micro grinding process are acquired, and then the relationship between the grinding temperature and the glass transition temperature of bulk metallic glass is observed. Consequently, the simulation of the grinding temperature of the bulk glass metal can effectively predict the crystallizing procedure of the grinding surface. With various micro grinding parameters, the temperature variation trend of the grinding zone of bulk metallic glass is observed. The simulation results show that the highest grinding temperature of bulk metallic glass occurs in the contact area between the abrasive rake surface and the grinding chips, i.e. the secondary deformation zone.
