正确选用内径表１引言内径表作为测量孔径的工具，在工矿企业中有着广泛的应用。怎样根据被测量的公差值来选择内径表，对此往往不予重视。本文根据测量能力指数Ｍｃｐ值来推算内径表在不同测量范围内的公差Ｔ值，从而为正确选用内径表提供依据。内径表可分为带定位护桥式... Correct choice of diameter table 1 Introduction ID meter as a measuring aperture tool, in industrial and mining enterprises has a wide range of applications. How to choose the diameter meter according to the measured tolerance value is often neglected. In this paper, according to the measured capacity index Mcp value to calculate the diameter of the diameter meter in different measurement range tolerance T value, so as to provide the basis for the correct selection of the IDT. Diameter meter can be divided into the position with the bridge protection ...
