How Does a Radius Gauge Help in Workshop Measurement?
A simple guide explaining radius gauge, its working, least count, size range, and role in accurate workshop measurement. What Is a Radius Gauge? A radius gauge is a precision measuring tool used to check the radius of curved surfaces. It helps identify whether a curve is concave or convex and measures its exact size. This tool does not give digital readings but works by matching the curve of the gauge leaf with the curve of the workpiece. Each gauge consists of several thin metal leaves. Every leaf has a different radius value marked on it. When a leaf fits perfectly on a curved edge without gaps or light passing through, that radius value is considered correct. This tool is commonly used on shafts, fillets, grooves, dies, moulds, and machined components where curved edges are required. Why Radius Measurement Is Important In machining and manufacturing, even a small error in radius can cause major problems. Incorrect radii can lead to stress concentration, poor surface finish, vibrat...
