英文摘要	To study the deformation mechanism of high manganese steel at high-speed machining and the influence of cutting parameters on a quality of machined surface and on a tool wear, we conducted a serial of tests cutting high manganese steel with metal ceramic tool. By observing the macroscopic chip and measuring its micro-morphology with optical microscope under the condition of five groups of cutting parameters, the effect of cutting speed and amount of feed on chip shape was analyzed. The main mechanism of chip deformation and its effect on chip morphology and tool wear has been studied, and a linear model of surface roughness has been built with regression test method for predicting machined quality. The results show that the deformation mechanism of high manganese steel at high-speed cutting is the concentrated shear or adiabatic shear, and the reason of tool wear is a coherent wear combining abrasive wear and oxidative wear. The model of surface roughness obtained can preferably be used to forecast the machined surface quality by given cutting parameters, or determine cutting parameters with the required roughness height.
