Micro-extrusion process is one of the micro-forming technology for fabrication of micro-parts such as micro-gear shaft for microelectromechanical system (MEMS) and micro pins for electronic parts. This paper presents the friction models effects and geometry effects on curving tendency of micro-extrusion 6063 aluminum alloy pins. Three friction models were considered: (1) Coulomb friction, (2) plastic shear friction, and (3) combined (Coulomb & plastic shear) friction. The finite element simulation was carried out and the results showed that the combined friction model accurately predicted the micro-extrusion results. Then, four tool geometry and position effects were investigated: (1) punch shift length, (2) die angle, (3) die shift length, and (4) bearing length. The finite element simulation was carried out to determine these tool geometry and position effects on the curving tendency of micro-extruded pins. The results showed that punch shift length and die angle did not affect the curving tendency. However, die shift length caused the micro-extruded pins to curve. The increase in bearing length helped straighten the micro-extruded pins.

The effect of cutting tool geometry on cutting process is very prominent and cannot be ignored, especially the interactions between tool geometries. In this study, the effects of the rake angle, the clearance angle, the cutting edge radius and the interaction between rake angle and clearance angle on cutting force and cutting temperature are numerically investigated using finite element method. Four-factor three-lever orthogonal experimental design is adopted in the finite element simulation of orthogonal cutting process. An analysis of range is performed to identify significant trends in the cutting force and cutting temperature and the optimal level values of each factor. The result shows that the effect of the rake angle on cutting force is significant. The effect of interaction between rake angle and clearance angle on cutting temperature also appeared to be important. Finally, the optimal parameter combinations of tool geometries for cutting force and cutting temperature are obtained, respectively.
