| Abstract: | Considering the effect of random factors， Monte-Carlo numerical simulation method was used to study the statistical distribution of cutting force in the process of metal cutting. The model of parallel shear zones unequally divided was established to solve the cutting velocity， shear strain rate and shear strain. Control equation of metal cutting materials and temperature control equation for shear zone were constructed to calculate shear stress and cutting force. Extracted samples from the distribution information of cutting parameters were substituted into the cutting force model to calculate the cutting force and its probability characteristics. Thereby an orthogonal cutting force prediction method was presented based on Monte-Carlo method. |
