| Abstract | The dynamic stiffness of workpieces during processing is a significant factor in grinding accuracy analysis. In this study, a non-contact measurement system based on electromagnetic excitation was developed to evaluate this dynamic stiffness. A grinding process simulation model incorporating contact dynamics was then constructed to predict grinding results. As a result of identifying the contact dynamics from the measured dynamic stiffness of the workpiece and applying them to the proposed simulation model, the grinding results of workpieces with varying stiffness levels were predicted with high accuracy. This is evidence that consideration of contact dynamics is essential for accurate prediction of grinding surface profiles of workpieces with low stiffness. |
