【Abstract】 A new and more accurate prediction algorithm for cutting forces is got from inverse problem of cutting force prediction and its solution process based on Oxley′s cutting model. The prediction process can show the dynamic variation of the relationship between the cutting parameters , cutting tool structure and the boundary conditions of rake face and material constant. The statistical results of cutting forces prediction show the mean error of main cutting force is about 1.289 6% and that of radial cutting forces is about 3.191 7%, the results show that this procedure especially can obtain good effects for high speed cutting.更多还原
