Recursive model of the blunting of an abrasive grain

An algorithmic model is proposed for calculating the blunting area of an abrasive grain in grinding. The model permits prediction of the blunting of an abrasive tool in a broad range of operating conditions. It is recursive: the nonlinear feedback with respect to the blunting area itself is taken into account. The model permits prediction of the performance of abrasive tools in different

Prediction on grinding force during grinding powder

It has been proposed by Zhang, et al. 35 that the plowing force is mainly produced by the plastic flow of material. Therefore, owing to the material plastic flow, the average grinding force per unit area F p is related to the grinding parameters (e.g. abrasive wheel speed v s, workpiece infeed speed v w and depth of cut a p) and some mechanical properties of the material (e.g. modulus of
