Modeling and Stability Analysis of SiCp/Al Composites Thin-Walled Workpiece in Rotary Ultrasonic Machining

Article Preview

Abstract:

Particle reinforced aluminium matrix composites could be used in manufacturing of aviation thin-walled workpiece due to its excellent performances, but it is hard to be manufactured. Rotary ultrasonic machining (RUM) is very suitable for machining particle reinforced aluminum matrix composites with moderate or high volume fraction. Chatter appears very easily in machining process of thin-walled workpiece and it can seriously reduce the quality of components. Based on the dynamic characteristics of machining process, a stability analytical model is built. It is analyzed that the process stability of a thin-walled workpiece of SiCp/Al composites reinforced with 45% volume fraction, and the stability lobe diagram is plotted by using MATLAB. According to stability analysis results, a machining experiment is conducted and the test results indicate chatter could be prevented effectively by this method.
