dc.description.abstract | A method of measuring shear friction factor between a workpiece material and a forming tool through a backward extrusion process. The method includes steps of: positioning the workpiece material at a groove previously manufactured on the forming die by turning; pressurizing the workpiece material to form an extruded product by pressure of a downwardly moving punch; forming tip on the extruded end of the extruded product; measuring an external diameter of the extruded product and a diameter of the tip, and obtaining a perpendicular distance by subtracting the diameter of the tip from the external diameter and dividing the subtracting result by two; and acquiring shear friction factor by calculating predetermined coefficients and a normalized perpendicular distance non-dimensionalized by thickness value of the extruded product. The thickness is defined as an interval between the external diameter of the extruded product and an external diameter of the punch. | - |
