摘　　要：针对标准量具尺寸、形状精度高、检定周期短、检测操作繁复等要求,提出了一种采用三坐标测量机进行精确、高效检测的新方法。选用Φ39.5015标准环规作为检测对象,设计了标准环规精准装夹定位、测量策略,分析优化了计算方法,编制了自动测量程序。测量结果与传统的常规测量方法对比发现:新方法的测量结果更精确,检测效率更高,有效解决了工程实践中由于检测效率低下而影响产品交付的难题,取得了良好效果。Aiming at the high accuracy in size and shape,short verification period and complicated operation situation of standard gages,a new accurate and efficient method of detection with CMM is proposed. The standard ring gauge of Φ39.5015 is selected as the testing object. The precise clamping positioning and measuring strategy of standard ring gauge are designed,the calculation method is optimized,and the automatic measuring program is compiled. Compared with the conventional measurement methods,the new results measured by new method with CMM is more accurate and detection efficiency increased by 40.63%.The problem of low detection efficiency affecting product delivery in engineering practice is solved by this method,and achieves good results.
