Abstract

<p>Vibrations during machining have a direct impact on the ground surface properties of the workpiece. This study focused on the vibrations caused by the abrasive-work interaction in cylindrical grinding, and the measurement and analysis of such dynamic behavior to determine the optimum dressing cycle. This dissertation describes a technique that can be adopted to continuously monitor the forces generated during the grinding operation, by using an in-process two-dimensional piezoelectric force sensor fixed on the tailstock center, which can simultaneously measure the normal and tangential forces, and also quantifies the force variation, which is due to the vibration. The relation between the variation of grinding force and transition of grinding ability as grinding progresses can be determined by FFT analysis of the variation in the normal and tangential force components individually, and by measuring the profile and surface roughness of the ground workpiece. Furthermore, the influence of dressing conditions on the grinding characteristics was experimentally examined based on the variation of grinding force. The results facilitated the development of an effective tool to determine and control the timing of dressing.</p>
