文章对JJG 343—2012《光滑极限量规检定规程》中形位误差、量规尺寸、作用尺寸等名词进行了解释,通过举例说明了如何依据规程中提供的技术参数在实际检定过程中计算量规极限尺寸。分析了规程中有关形位误差与尺寸误差之间的关系及两者关系对检定结果的影响,对检定证书格式中有关量规尺寸如何给出进行了探讨,同时指出了规程中存在的一些错误信息。
This article explains the terms of position error, gauge size, acting size and other terms in JJG 343-2012 Smoothing Limit Gauge Verification Procedure. By way of example, it shows how to calculate the gauge limit size in the actual verification process according to the technical parameters provided in the procedure . The relationship between shape and position error and size error and the relationship between the two are analyzed in the protocol. The relationship between the two is discussed. And how to give the gauge size in the verification certificate format is discussed. At the same time, some error messages .
