Abstract

Tool overhang length tuning by matching the modes of tool-extension-holder-spindle (TEHS) assembly components creating dynamic absorber effect is one of the rare chatter suppression techniques. In some milling applications, a tool holder extension may have to be used to increase the overall tool overhang length for reaching far sections of the workpiece. In this work, design parameters of the holder extension are optimized to maximize the dynamic absorber effect resulting from modal interactions among the components of the TEHS assembly. Improvements in the dynamic rigidity and chatter free Material Removal Rate (MRR) are demonstrated through simulation results.
