In the present time, to make any part interchangeable and to increase mass production, it is important that a job or workpiece should be prepared according to the drawing tolerance and limit with the help of a caliper or other instruments.
It is possible to prepare an accurate job but it is very time-consuming. Thus, it affects the production, it decreases the production. This is not only the reason for less production but also the illiteracy of the workers as they feel difficulty reading instruments. To overcome these problems for mass production and to make jobs interchangeable, gauges were invented.
A gauge is a device, which is used for measuring or checking a job to control the size during or after the process of manufacturing in order to establish the interchangeability.
In this chapter, we will study the different types of gauges, their specifications, uses, and all other related aspects.
Importance of GaugeÂ
(i) It saves time to check the job.
(ii) Less supervision is required and less rejection of jobs.Â
(iii) The cost of production decreases.
(iv) Part interchangeable can be made.
(v) It is user-friendly so that even unskilled workers can do the work.
Classification of Gauges
Measurement instruments come in all shapes, sizes, and types to measure everything from chemical properties to electrical parameters. Here, we will discuss the different types of gauges that enable the measurement of physical dimensions.
