Radius gauge is used to check-

Explanation:

Radius gauges:

• Radius gauges are used to check the internal and external radius of workpieces.
• These gauges are made of high-quality steel sheets and are finished to an accurate radius.
• Radii of parts are checked by comparing the radius of the gauges.
• Radius gauges are available in sets of several blades held in a holder.
• Each blade can be separately pulled out of the holder when in use.
• The size of the radius is marked on the individual blades of the gauges.
• These gauges are available in different combinations with internal and external radii.
• Individual gauges are also available for different radii.
• The other typical applications are:
• Checking the corner radius of a part being filed to shape.
• Checking a radius formed by a milling cutter.
