Deformation Characteristic of a Double Structure Blade under Continuous Cutting Condition Using a Crank Type Machine

Abstract

This paper reports on deformation characteristics of a double structure blade under a continuous cutting condition using a crank type machine. From this research, the following results were found: (1) Deformation of the bottom tip at a certain applied force has prevented the blade cutting tip from severely damaged. (2) A plastic deformation was found on the bottom tip at a certain applied force and has resulted in a decreasing of force balance. (3) Crushed tip thickness t_C1 tangency, measured along the blade cutting line showed a little reducing especially at high applied forces resulted from the bottom tip ‘shimming’.
