摘要：

A method is proposed for estimating the value of the shear friction factor using a backward extrusion-type forging. This method uses forging load multiplied by the bottom thickness in a backward extrusion test as a measure to calibrate the friction factor. The advantages of the proposed method are: (1) the friction factor can be determined for forming processes where the interface pressure is high and new surface generation is large, e.g., cold forging and precision forging, and (2) the value of the friction factor can be determined continuously during the forming process. Thus, the performance of a lubricant during the entire test can be monitored.
