| Popis: | To suppress chatter is very important for ensuring processing quality and efficiency in ultrasonic-assisted grinding of thin-walled workpiece of SiCp/Al composites. Based on the chatter mechanism analysis, a stability analysis model is built and the analytical method is proposed. The cutting parameters can be selected reasonably based on the lobe diagram of stability, and the experiments were conducted using the parameters of selected points on lobe diagram. The experimental results show that the cutting force and surface roughness of unstable points are much larger than that of stable points, the vibration marks appear on the workpiece surface with unstable machining, and the surface quality is better in stable machining, which indicate that the chatter could be suppressed by this method to guarantee machining quality and efficiency. |
