- Abstract:
- Direct extrusion shaping creates friction on the tool surfaces due to relative motion of the tool materials. Friction increases the necessary extrusion force and causes extrusion faults by changing the material flow mechanism. A number of parameters affect the magnitude of extrusion force. Being one of these parameters, the lubrication effects the friction and therefore defines the extrusion force in friction. In this study, the effect of lubrication on the extrusion force is theoretically and experimentally studied. In the experiments done, the parameters such as extrusion ratio, die angle and lubrication are changed and the extrusion forces are determined while the other parameters are kept constant. After a sufficient and homogeneous lubrication, the material flow becomes steady and uniform and the extrusion force is reduced.
