| Abstract: | The presence of contact stiffness and the contact damping in mechanical bonding surface, has influence on the machining quality of part surface. This paper presents a method of calculating the contact stiffness and foundation damping during elastic floating grinding, the grinding system is equivalent to two single degree of freedom system and coupled into a two degree of freedom system. The relationship of amplitude A and the time t in the grinding process is measured by experiments, and then the contact stiffness and the contact damping are obtained by curve fitting method. |
