In order to research the ploughing extrusion angle influence on cutting performance and realize the virtual design and manufacture of ploughing-extrusion forming cutter, the plough-extrusion forming process of wick micro-groove structure was simulated by DEFORM-3D software. The micro-copper tube with diameter of 6 mm was simplified to 0.4 mm thick copper plate in this paper. In the simulation process, only the single parameter of tool extrusion angle was changed (45°, 60°, and 90°). The structure, stress and strain distributions of copper plate fins formed by three kinds of extrusion angle cutters were analyzed. It is concluded that the plough-extrusion cutting performance of 60 degree extrusion angle cutter is the best. Nowadays, with the rapid development of microelectronic technology, the heat flux density of microelectronic products has increased dramatically. Because of the characteristics of high heat transfer efficiency, high heat dissipation property, good isotherm property and no need of extra power source, heat-pipes with wick micro-groove structure are widely used to solve the thermal control and conduction of products with high heat flux density[1-5]. The manufacturing forming of wick micro-groove structure is the key problem of micro heat pipe technology. Plough-extrusion forming process solves this problem, so the key problem changes to the design and manufacture of ploughing-extrusion forming cutter[6-9]. Compared with the traditional design and manufacture methods, finite element simulation technology is becoming more and more popular among experts and scholars because of its time-saving (short cycle), low cost and high-precision. Chen designed the geometric structure of the ploughing extrusion forming tool and carried out the cutting experiment of the designed tool [10]. Through a novel ploughing-extrusion process, wang solved the problem of heat pipe low heat transfer performance manufactured by traditional manufacturing methods[11]. Based on wang’s research, Tang validated the high heat transfer performance of heat pipes manufactured by the novel ploughing-extrusion process [12].
