Using the single factor experiment method , the finite element simulation of Ti6Al4V cutting was done based on the software ABAQUS in different rake angles .The generation procedure of serrated chip was analyzed and the mechanism of serrated chip formation was investigated deeply .The influences of the rake angle of tool on the variation of serrated degree and cutting force were also analyzed .The result of the investigation showed that the rake angle had an important influence on the serrated chip formation ,and the cutting force and the serrated degree of chip we...
