Controllable Variable Simulation in Computer Controlled Optical Surfacing
光学技术与仪器 大偏离量非球面 去除函数 平转动 optical technique and instrument large departure aspherics removal function motion in planar model
摘要
由描述计算机控制光学表面成型(CCOS)的Preston方程出发,针对磨头平转动加工方式,建立了工件与磨头之间的相对运动关系。在此基础上,模拟计算了除驻留时间以外的控制参数(磨头驱动电机转速)对CCOS加工质量的影响,为进一步优化原有的数控模型、增加可控变量、从而实现大偏离量非球面的快速加工提供了理论参考。
Abstract
In this paper, on the basis of Preston hypothesis, kinematic principles are applied to deduce the motion relationship between tool and workpiece upon the tool's motion in planar model. From that the effect on CCOS (Computer Controlled Optical Surfacing) caused by controllable variable except dwelling time is analyzed by computer simulation. Thus, provide some reference on theory to optimize the former NC model, add a controllable variant, and realize the large departure aspherics fast manufacture, so planar motion can be applied in CCOS to converge the figure error.
