What are the different types and uses of plug gauges?
Plug gauge, also known as pin gauge , is a metrology tools which is used to measure the inner diameter of a hole that has been drilled or machined into a manufactured part, component, or assembly. This is an essential tool for quality control, and it enables the inspectors, machinists, manufacturing engineers, and others to quickly obtain a go/no-go decision about whether the inner diameter being measured falls within the specified dimensional tolerance. This measuring process is designed to allow accurate assessments to be made without the need for the production personnel to use an addition of more sophisticated and/or more expensive measuring instruments such as inside micrometers. In production operations, where a large volume of parts is being produced, plug gauges provide a rapid means of assessing the quality without taking time to perform actual hole diameter measurements and to set-up instrumentation. When using plug gauges , it is important to acknowl...
