Abstract
On prior studies, it is showed that low frequency vibration drilling suppress the tool chip temperature rising and extend the tool life. Yet, particular mechanisms are not known. Researching the principle, allows to setup in an effective parameter for drilling difficult-to-cut materials at high efficiency. In this study, the cutting heats at each point of the tool were calculated. And by that, unsteady heat transfer analysis was simulated. Also, simulation results and experiment results was compared for checking the validness.
