《计量技术》85年第一期发表的《锥孔测量指示器》(以下简称《指示器》)一文,介绍了一种用于批量生产中的锥孔测量指示器,并介绍了偏差计算方法。我认为《指示器》的偏差计算方法没有考虑测量方法的不确定度,不符合《光滑工件尺寸的检验》(GB 3177—82)的验收原则,即“所用验收方法应只接受位于规定尺寸极限之内的工件”的原则。下面以《指示器》示例中的数据(D_0=11.862,d_0=8.444,α_0±δα=12°55′±45″,α±△α=13°±5′)对锥孔锥度测量指示器进行计算说明。
A “Cone Measuring Indicator” (hereinafter referred to as “Indicator”), published in the first issue of Metrology Technology in 1985, introduced a conical bore measuring indicator for use in mass production and introduced a method for calculating the deviation . I do not think the “indicator” deviation calculation method takes into account the uncertainty of the measurement method and does not comply with the acceptance principle of the “test of smooth workpiece dimensions” (GB 3177-82), that “the acceptance method used should only be accepted at the limit Within the workpiece ”principle. The taper taper measurement indicator is made below with the data in the “indicator” example (D_0 = 11.862, d_0 = 8.444, α_0 ± δα = 12 ° 55 ’± 45 ", α ± Δα = 13 ° ± 5’ Calculate instructions.
