In the manufacturing industry, the production of component is governed by the international standards. Each of the standard has about set tolerances and dimensional limits, which the manufactured component should meet for it to be accepted in the industry. The dimensions therefore need to be examined and checked and the findings of these checks are recorded. A complete series of metrology equipments is available in the market for measuring lengths, diameters, and surface finish.
There are several methods and tools available for checking thread dimensions when a threaded component is manufactured. The effective pitch diameter of a thread is measured using thread micrometer, and it is fitted with conical anvil and a vee. This can also be achieved through thread wire sets and standard flat face micrometer. The thread gauges are used for checking whether the thread dimensions fall under or over dimensional limits. The thread gauges are ground and hardened to accurate dimensions which meet the specification for required standards.
The thread plug gauges are used for checking internal threads while the thread ring gauges are used for checking external threads. Basically each gauge consists of two fundamental parts in the form of GO gauge and NO GO gauge. Both of the parts must be utilized accordingly for checking the thread. For the thread to be well within the permissible dimensions, the GO plug gauge must screw into internal thread and the NO GO must not screw into it. The gauges are available for various sizes and forms including 60 degree form, 50 degree form, and acme form.
