Abstract
This paper describes the effect of the tool length on achievable stable metal removal rate in high speed milling. Through finite element computation and experiment, it is shown that the tool length most strongly affects the natural frequency of the most flexible mode. The change in frequency changes the most stable speed in the stability lobe diagram. The highest metal removal rates occur when the tool length is selected to match the stable zone to the highest spindle speed. Sometimes longer tools can provide higher metal removal rates than shorter tools because they utilize the stability lobe phenomenon more effectively.
