| Abstract: | The deforming process in metal forging is simulated through the compression test in which several workblanks of different size are tested on the tools with different surface roughness.The influence of the geometrical size of workblanks and the friction state on the forging deformation load and the deforming process is analyzed.The change in the specific roll pressure of workblanks is investigated as the tool surface roughness and the relative height of workblanks are changed. Based on the test results, several points which should be paid attention to in practical production are discussed. |

| Keywords: | friction relative height unit deforming force technology of die forming surface roughness |
