Simulation Research on Ploughing Extrusion Angle Influence on Machinability

Abstract

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.
