由中国计量科学研究院和昆明机床厂共同研制的高精度环形激光测角仪已于1983年12月26日在昆明通过国家鉴定。 它是以环形激光器为测角元件,并采用了自动计数、空气轴系、微处理机实时处理数据等先进技术制成的新型高精度测角仪,测量效率高。经鉴定,检测一次测量光栅盘直径间隔的准确度为0.16″,环形激光器的系统误差(直径误差、峰峰值)f_(max)=0.02″。
The high-precision ring laser goniometer jointly developed by China Institute of Metrology and Kunming Machine Tool Plant passed the national appraisal in Kunming on December 26, It is based on ring laser angle measurement components, and the use of automatic counting, air shaft system, microprocessor real-time processing of data and other advanced technology made of new high-precision goniometer, high measurement efficiency. After verification, the accuracy of measuring the grating disk diameter interval is 0.16 “. The systematic error (diameter error, peak-to-peak value) of the ring laser f max = 0.02”.
