Simulation of Roll Grinding System With Double Regenerative Chatter

In this paper dynamical analysis of a grinding process in steel roll manufacturing is studied. The main sources of the regenerative chatter are the time delay effects from both work piece and tool surfaces. The dynamical behaviors of the system have been described in a multi-degree-of-freedom (MDOF) simulation model and both responses of the roll and the grindstone motions have been considered. The conventional controllers are included in order to achieve the desired rotational speeds of the two spindles. The simulation results of the model with double time delays will be carried out and the special characteristics of the system stability relative to delays will be discussed through analysis.
