Research output: Contribution to journalArticlepeer-review


The Dynamic Data System (DDS) methodology is used to reveal the grinding process dynamics from the cutting force signal. The discrete DDS models are fitted to 16 sets of cutting force signals and the models as high as tenth order are obtained. From the analysis of the discrete models, the natural frequencies corresponding to characteristics subsystems such as machine tool and dynamometer, the effective grit pass (EGP) and the grinding wheel contact dynamics are identified. An exploratory attempt is made to analyze the continuous DDS model leading into a qualitative interpretation of the possible coupling phenomena.
