螺纹的综合测量和单项测量

Measurement of Single Parameter and Synthetical of Thread

简要介绍了螺纹测量的现状和目前存在的问题,讨论了螺纹测量需要研究的几个问题,分析了螺纹单项参数测量和综合测量的关系以及螺纹量值传递技术。具体介绍了实现内螺纹中径参数测量的测量原理、测量方法和测量中的问题。

This paper firstly gives a general introduction of the present stitus and problems of the thread verification. Furthermore, this paper discusses several issues of thread verification needed to be studied and analyses the relation between the single and sythetical parameters measurement of the thread and the techology of the dissemmination of the value of a quantity. In the following, this paper focuses on a detailed description of the measurement principles and the measurement methods and the problems in measurement about effective diameter of internal thread measurement.
