A General Material Removal Model for Multi-infeed Internal Plunge Grinding by Using Power Signal

In order to monitor grinding accurately and efficiently, the paper deals with simulation of the multi-infeed internal plunge grinding processes and presents a general material removal model. The power signals of spindle motor that occur during the plunge grinding are obtained to build the grinding power signal model (GPSM) for this multi-infeed internal plunge grinding processes. The proposed model could be effectively used to monitor and control the whole internal plunge grinding processes. At last, the results of the experiments confirm the validity of the general model.
