“…They used various surface treatment to explain the influences of friction condition on the process and how improve the quality of the products and reduce the force of friction on contact areas and decrease the cost of production by increase die life . This has been done by control the important properties such as hardness , toughness and wear resistance at high temperatures which ensure continuance for good grade of parts production [1]. A Farhoumand et al used finite element techniques to demonstrate the effect of process condition for example friction effects during combined extrusion process by using ABAQUS method .…”

During extrusion process ,the effects of friction between die and workpiece are important and it is one of the most serious problems in metal forming. Friction factor has different effects depending on the size of workpiece. In this study the effect of friction factor and lubrication effects on temperature distribution , power , and load for combined backward forward extrusion process was demonstrated . A numerical analysis based on finite element method by using Q form program was used to study the effect of friction factor through two type of condition , first for lubrication three values for friction factor were used ( 0.1, 0.2 ,0.3 ) .The second condition was un lubrication , the friction factors values were (0.25 , 0.5 ,0.75) . The material of specimen was steel C45.The parts to be manufactured was wrench socket and the lubrication was done by using water and graphite .The results showed that for lubricated and un lubricated conditions , the temperatures power and load were increased when the friction factor increased .
