Abstract
The grinding force prediction model based on random morphological characteristics of grains was proposed in this chapter. Firstly, a grain randomized grinding wheel surface morphological model is constructed based on the geometric characteristic of grains, and the mechanism to determine effective grains in the grinding zone is disclosed. According to kinematic laws of grains, the material removal mechanism during grinding of Ti alloy is analyzed. Furthermore, influencing mechanisms of randomized geometric and spatial characteristics of grains on effective action area are discussed based on mechanical behaviors of grain-workpiece interaction in different stages, thus getting the calculation formula of grinding force of a single grain. The theoretical model for grinding force prediction is constructed by combining with number of effective grains in different stages. Numerical simulations are carried out to disclose dynamic variation of grinding force. Finally, the variation laws of grinding force under different CAMQL parameters are investigated.
