摘要
分析了球面、非球面等大型二次旋转曲面精密磨削原理,提出了一种只需2个直线运动和1个摆动运动就可以实现球面、非球面等大型二次旋转曲面精密磨削加工的方法.在此基础上,提出了一种基于法线跟踪的面形精度在位实时检测方法,并设计了大型旋转曲面智能精密磨削系统.结果表明,采用所提出的方法能够使砂轮主轴旋转中心线与二次曲线上磨削点的法线重合,从而提高磨削精度和磨削效率.
The precision grinding principle of the spherical, aspherical and other large two revolving curved surface was analyzed. Besides, a novel method for grinding large rotating conicoid with two linear motion and a rotation was introduced. Moreover, an approach for a real-time detecting surface precision based on normal tracking was proposed, and the intelligently precisely grinding system was designed. The results show that with the application of this method, the grinding spindle rotation center line coincides with the normal line of the ground point on the quadratic rotated conicoid, thereby, improving the grinding accuracy and grinding efficiency.
