国内大型非球面的加工流程一般是先精磨成最接近球面,然后抛光修磨成非球面。由于这种方法抛光效率低,所以整个流程的加工周期很长。提高加工效率的方法之一是在精磨阶段就将其修磨成非球面,为此提出了一种采用较大磨盘,由自校正模糊补偿控制模型控制环带精磨非球面的方法。试验结果表明,采用该方法可以得到精磨成型非球面,从而提高了大型非球面的整体加工效率。 Domestic large-scale aspheric processing is generally first refined into the closest spherical, and then polish grinding into aspherical. Due to the low polishing efficiency of this method, the entire process has a long processing cycle. One of the ways to improve the machining efficiency is to grind it into aspherical during the refining stage. To solve this problem, a method of controlling the aspheric surface by a self-tuning fuzzy compensation control model is proposed. The experimental results show that the aspheric surface can be finely ground by this method and the overall processing efficiency of the large aspheric surface can be improved.
