摘要
为提高巨型工件大直径测量精度,可将直径的测量转化为弦及弦高的测量,但其刻度是非均匀的,如果采用光电数字式测量,可以改善性能,实现高精度的测量。
In order to increase the measurement precision of the big diameter of giant workpieces, one may convert the measurement of diameter into the measurement of string and its height, but the graduation is not even. However, if photo electric and digital measurement is used, the performance may be improved, and the measurement of high precision will come true.
