Modelling and analysis of grinding energy consumption in non-circular grinding plays an important role in the low-carbon processing for the mass production of the complex shaft parts, such as the crankshaft and camshaft. An empirical model of the grinding force is established based on the movement characteristics of non-circular grinding process. And then the mathematical models of the torque applied on the part and the corresponding grinding energy consumption are built up according to the analysis on the grinding force acting on the part. The result of the simulated calculation by the torque model demonstrates that it is affected greatly by the ratio of the tangential and the normal grinding force among all the model parameters. The multi-objective constraint optimization problem for the optimal parameter λ is proposed by constructing the relative errors of every sample values and the peak-peak value between the calculated torque and the measured one. The experimental results verify the accuracy and reliability of the torque model whose parameters are identified by the proposed method in non-circular grinding of the eccentric shaft in the RV reducer. And also the influences of the different grinding parameters and the material removal rate on the grinding energy consumption are analyzed based on the proposed energy consumption mathematical model which helps the grinding parameter optimization and the energy-saving in non-circular grinding.
