利用光电自准直仪和多面棱体配合,提出了一种进行转台角位置精度的直接测量方法,分析了误差因素和方向,给出了减小测量误差的算法。实测数据验证了方法的可行性。
A direct method of measuring the position accuracy of rotary table is proposed by using the photoelectric autocollimator and multi-faceted prism. The error factor and direction are analyzed, and the algorithm to reduce the measurement error is given. The measured data verify the feasibility of the method.
