Abstract
For the purpose of revealing the formation characteristics of the chip and analyzing damage equivalent stress of the cutting tool in high-speed intermittent cutting, cutting tests, and finite element simulation were performed in the present work. Characteristics of chip morphologies acquired in cutting tests were analyzed and compared for different cutting conditions. The effects of cutting parameters on force, temperature, and stress on the shear plane were investigated. On the basis of the concept of damage equivalent stress, the initial damage of the cutting tool and the tool stress were integrated and the influences of cutting parameters on damage equivalent stress were studied. The correlations between damage equivalent stress of the cutting tool and chip formation were analyzed. Analysis results indicated that there existed strong correlations between the evolution of damage equivalent stress of the cutting tool and the chip formation process. Relatively low damage equivalent stress and relatively long tool life appeared at the same time when small values of cutting speed and feed rate were used.
