Analyzing the Effects of Tool Holder Stiffness on Chatter Vibration Reduction in Turning

This paper investigates the effects of tool holder materials on chatter vibration in turning operations. The study uses a complex dynamic turning model with two degrees of freedom for the orthogonal cutting system. Tool holders made from different materials, including Al 5083, Al 6082, Al 7012, and a standard 4140 material, were subjected to chatter vibration to investigate their process damping capabilities. The study found that the standard tool holder 4140 allows for higher stable depths of cut and produces similar process damping values compared to the other tool holders. Finite element analyses (FEA) were performed to verify the experimental results, and the modal and FEA analyses produced very similar results. The study concludes that future research should investigate the effects of tool holders made from high alloy steel alloys on process damping. Overall, this paper provides important insights into the effects of tool holder materials on chatter vibration and process damping in turning operations, which can help in the design of more efficient and effective cutting systems.
