摘要
光学球罩被广泛应用于各类光电系统中,其面形精度制约着光电系统的成像质量。随着数控技术的发展,数控加工技术逐渐成为目前光学加工行业的主流发展方向。基于高质量的铣磨表面,为了能够在准球心高速抛光工艺中实现等去除量加工,本文对同步抛光技术进行了理论分析及数学模型推导,并通过实验证明,同步抛光技术可以有效地提升加工效率,获得高质量的光学表面。
Optical spherical shell has been widely used in many optoelectronic systems;meanwhile the imaging quality is limited by its surface precision.Based on numerical control technique and high quality grinding surface,in order to achieve equal-remove rate polishing process,synchronized polishing technique is deduced by mathematics in this paper.With this technique,the polishing efficiency and optical surface quality has been promoted.
