Explanation:

  • Components manufactured using mass production methods are checked only to ensure that the sizes are within the prescribed limits. 
  • The most economical method of checking such components is by using limit gauges.
  • These gauges are used in inspection because they provide a quick means of checking.

Go and No Go principle:

  • The Go and No -Go principle of gauging is that the Go - end of the gauge must go into the feature of the component being checked and the No - Go end must not go into the same feature.
  • The dimensions of the Go and No-Go ends of gauges are determined from the limits stated on the dimension of the component to be gauged.
  • The dimension of the Go-end is equal to the minimum permissible dimension and that of the No-Go end is equal to the maximum permissible dimension.
