The paper based on the idea of the virtual design, simulated the process of the orthodoxy metal cutting through the technology of number imitation which based on the general international large software ANSYS precisely and vividly. With this method, this paper analysised the form of the shearing area and the change process of the stress and strain, and acquired the distribution of the contact load of the cutting tool with which we studied the distribution of the stress of the cutting tool. We carried throug...
