An acceptance gauge is a type of inspection tool used in manufacturing to determine whether a component conforms to defined dimensional tolerances. It typically uses a Go/No-Go system to quickly check whether parts are within acceptable size limits. The “Go” end must fit the part, while the “No-Go” end must not. This simple yet effective method ensures quality, consistency, and reliability in mass production, particularly in industries like automotive, aerospace, and precision engineering. Acceptance gauges play a crucial role in reducing measurement errors and speeding up the quality control process.
