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 .
