A go/no-go gauge refers to an inspection tool used to check a workpiece against its allowed tolerances via a go/no-go test. Limit Gauges, like any job, require a manufacturing tolerance, and the theoretically gauge size is determined by the lalylor’s principle of gauge design.

Tolerances are used to control the amount of variation inherent in all manufactured parts. maximum p.d. Its name is derived from two tests: the check involves the workpiece having to pass one test (go) and fail the other (no-go).. For example, ISO 1502 sets a standard for screw threads and gauging to test them. Placement of all text to be read from the bottom of the drawing is called unidirectional dimensioning. Logically the manufacturing tolerance (gauge tolerance) should be kept as small as possible, so that a large proportion of the work tolerance is still available for manufacturing a component. 29 Gauge Tolerance: Normal practice is to take gauge tolerance as 10% of the work tolerance. 2, 3/10/09 4 The Owner and Designer are responsible for compliance with the personnel and process qualification requirements of the codes and standards.
