Development of Optimal Tool Holder Selection Technology Based on Chatter Stability Index

Abstract

Since the compliance transfer function of the tool tip, which affects chatter stability, varies depending on the type of tool holder, it is important to select the optimum tool holder. In this study, we have developed a method for selecting the optimum holder based on the chatter stability by predicting the compliance of the tool tip when the tool holder and tool are combined. By applying this method to machining with a radius end mill, it was confirmed that the tool holder with the least chatter vibration can be selected from four types of tool holders.
