A position gauge is a precision inspection tool used in manufacturing and metrology to check the positional accuracy of features such as holes, slots, or surfaces on a component. It ensures these features are located exactly where they should be, according to engineering drawings or CAD models, relative to datum points or reference axes. Position gauges help control geometric tolerances like true position and are critical for components that require precise assembly alignment or mating with other parts. They are commonly used in quality control processes in industries like automotive, aerospace, and mechanical engineering to maintain tight positional tolerances and ensure proper fit and function.
