Abstract: The research of the grinding process modeling and simulation is presented. The development progress and its tendency of three types of modeling methods and simulation are described results, which are based on empirical analysis, theoretical analysis and finite element technology. The method of modeling and simulating results are discussed respectively in detail. Meanwhile the limitations of application of models are analyzed. It is indicated that the empirical models are based on finite data of experiments, which have low level of prediction abilities, the theoretical models which are set up on ideal assumption is complexity, and the finite element models are restricted to analyze the process of single-grit grinding due to technical problem, on that account, the methods of grinding process modeling and simulation research based on the regular abrasive distribution grinding wheel are introduced. Furthermore, their present situation prospect and significance for prediction, optimization and control of high speed and high efficiency grinding are elaborated.

Key words: grinding process, modeling, optimization, prediction, simulation
