英文摘要	Cylindrical grinding process is a complex phenomenon with several vibration excitation parameters that lead to the grinding wheel oscillation and workpiece deflection. In this work, a new model of the cylindrical grinding process vibrations is developed to analyse a particular type of dynamic instability induced by the in-feed rate. The grinding wheel is modelled as a constant speed moving oscillator excited by the grinding forces to provide a time-varying excitation load to induce the workpiece deflection. The workpiece is regarded as a simply supported non-uniform Euler-Bernoulli beam. The numerical analysis is used to obtain the governing equations of the process dynamics. MATLAB is used to obtain the dynamic response of the process. The experiment is used to validate the model simulation results. The results of the tested grinding mode show that the dynamic stability of the process is improved at the in-feed rate of 0.01 mm/s while reducing the grinding time.
