| dc.description.abstract | The objective of the research is to study the practical application of Variable Speed Machining (VSM) as a strategy to control regenerative chatter in end milling. In this research, experiments are conducted on a Bridgeport Discovery Torq-Cut 22 vertical machining center. The implementation of VSM on the machine is done with minimum hardware changes and minimum cost thus making it practically feasible. The cutting force data and the audible data where collected from the experiments and analyzed. In order to analyze the force data, the frequency profiles where studied and it was found that VSM had a suppressing effect on regenerative chatter compared to Constant Speed Machining (CSM). To validate the results obtained from the experiment, simulations are performed on a process model. For the purpose of simulations a simple single degree of freedom model is considered. The model yields a linear differential equation with periodic coefficients and delay terms. The simulation results mimic the behavior of the experimental results. Hence the potential of using VSM as an open-loop control for chatter looks promising. | en |
