Chamfer vs Fillet vs bevel: What's the Difference in CNC Design?
Quick Answer: Fillet vs Chamfer vs Bevel A fillet is a curved transition between two surfaces, defined by a radius. It is commonly used to reduce sharp internal corners, improve stress distribution, and support manufacturability. A chamfer is a flat, angled surface that removes a sharp edge. It is commonly used for deburring, edge protection, and facilitating component assembly. A bevel is an angled edge or surface, often used for larger edge preparations, cutting, and welding. In general machining and CAD terminology, bevel and chamfer can overlap, but their precise meanings depend on the application. The basic rule: Choose a fillet when a smooth radius is functionally important, a chamfer when you need a controlled angled edge, and a bevel when you need a defined sloping surface or specialized edge preparation. 1. What Is a Fillet? A fillet is a rounded transition between two intersecting surfaces. Instead of allowing two surfaces to meet at a sharp corner, a fillet introdu...
