A unique method to calculate both working stiffness and damping coefficient between grinding wheel and workpiece has been adapted to evaluate the grinding condition during grinding process. The relative displacement between wheel axis and workpiece is measured and Fourier transformed to calculate these parameters. This calculation is preceded corresponding to the constant interval of grinding stock removal continuously under the certain grinding condition. The calculated stiffness showed characteristic behavior from the start of grinding process to the end of wheel life. The calculated damping coefficient showed the negative value corresponding to the unstable grinding condition. Further, the relation between the dynamic balance factor and these calculated parameters are evaluated with regard to the grinding stock removal. In this report, the capability of the monitoring method to detect the state of grinding process is evaluated by using the calculated parameters
