The aim of this study is to find the best cutting conditions as analyzing cutting process of paper shredder and shape of cutter. The test has been done variation of torque and cutting velocity according to load. When shape of cutter and distance between cutter and shaft are changed, The variation of cutting force according to cutting angle and load is geometrically analyzed. The result of geometrical analysis is presented that the radius and array of cutter is the method to improve torque of paper shredder. In this paper it is presented as basic method of design to improve cutting performance of paper shredder.
