What is the Difference between fillet radius and corner radius?

Fillet radius refers to the rounded edge created between two surfaces, typically in 3D modeling or machining, to improve aesthetics or reduce stress concentrations. Corner radius, on the other hand, specifically refers to the radius at the corners of a shape, often used in 2D designs or profiles. While both terms involve curvature, fillet radius is more general, while corner radius is a specific application of that concept.
