| Abstract: | The experiments of the typical product in com-drawing steels have being carried out with different diameter raw materials and different angle dies.According to the drawing force data,we have made a parameter estimate with the nonlinear regression,revised the upper-bond method formula of drawing stresses calculation,improved the forecast precision of drawing forces. |
