【摘要】：提出了大型光学镜面变压强的高效研磨方法.传统研磨中普遍采用常压研磨的方式,很大程度上阻碍了去除率与收敛率的进一步提高.大量实验表明去除效率与压强之间并非线性关系,本文从研磨盘、磨粒与工件的几何学关系推导变压强条件下有效磨粒的分布规律,进而建立压强、磨粒运动形式与材料去除方式的映射关系,研究变压强条件下材料去除机理以及磨粒运行轨迹的微分几何描述,进而推导变压强条件下的非线性去除函数;通过音圈电机驱动的变压强研磨工具,利用机器人研磨平台实现了大型光学镜面的变压强高效研磨.
[Abstract]:An efficient grinding method for large optical mirror with variable pressure and strong pressure is presented.In traditional grinding, atmospheric pressure grinding is widely used, which greatly hinders the further improvement of removal rate and convergence rate.A large number of experiments show that the relationship between removal efficiency and pressure is not linear. In this paper, the distribution law of effective abrasive particles under variable pressure is deduced from the geometric relation of grinding disc, abrasive particle and workpiece, and the pressure is established.The mapping relationship between the motion form of abrasive particles and the material removal mode is studied. The material removal mechanism and the differential geometric description of the movement path of abrasive particles under variable pressure are studied, and the nonlinear removal function under variable pressure is deduced.By means of variable pressure grinding tool driven by voice coil motor and robot grinding platform, variable pressure and high efficiency grinding of large optical mirror surface is realized.
