Abstract
Heat generation in high-speed cutting causes various troubles. It makes a tool life short and accuracy of machined surface worse. In this study, tool temperature behavior in high-speed milling is simulated using finite element method. This report, it is analyzed that the transitional thermal behavior in short cutting time by loading intermittent heat flow is superimposed on the steady state of tool temperature. It is compared with experimental result with thermo infrared imaging camera, then heat flow ratio into tool and heat convection to air are determined.
