大型曲面柔顺抛光材料去除的理论建模及实验研究
Modeling and Experimental Investigation on the Material Removal in the Large Surface Compliant Polishing Process

针对大型曲面柔顺抛光过程中的材料去除问题，重点对柔顺抛光工具与工件表面接触区域的材料去除量进行建模，并推导出影响材料去除量的主要因素是摩擦系数。基于柔顺抛光工具系统和数控铣床建立实验平台，进行了大型曲面柔顺抛光过程的摩擦系数实验和电机电流监测实验。结果表明，接触区域内随着抛光工具驻留时间的延长摩擦系数呈增大趋势，电机电流与抛光力之间存在实时对应的关系。理论与实验相结合，验证了摩擦系数对材料去除量的影响。
To solve the problem of the material removal rate in the large surface supple compliant process, the material removal volume is modeled for the contact area between the supple polishing tool and the large surface. The coefficient of friction is the main factor to inluence the material removal is deduced. Based on the large surface supple polishing tool system and CNC milling machine, the experimental platform has carried out for friction coefficient test and motor current monitoring. The experiment results show that the coefficient of friction increases with to the increasing of dwell time, the existence of the corresponding real-time relationship between the motor current and the polishing force. The combination of the theoretical results with the experiment verifies that the influence of the friction coefficient on the amount of material removal
