Types of Bevels in Engineering and Manufacturing
Bevels are angled edges or cuts commonly used in woodworking, metalworking, and glass fabrication for both functional and decorative purposes. Key types of bevels include plain bevels, compound bevels, and chamfers, each serving different applications.

Standards |
| Standard Bevel | Single flat angled edge | 30°, 45°, 60° | Milling, grinding, laser cutting | Deburring sheet metal, weld prep | ISO 13715 (Edge Designation) |
| Compound Bevel | Dual-angle combination (e.g., X-type groove) | Dual 45° or 30°+60° | CNC milling, edge planing | Thick-plate welding (pressure vessels, shipbuilding) | AWS D1.1 (Welding Code) |
| Radius Bevel | Curved transition (convex/concave) | R0.5mm-R10mm | Ball-nose milling, rotary filing | Medical devices, fluid components (reducing turbulence) | ASME B46.1 (Surface Texture) |
| J-Bevel | Steep single-angle + root face | 50-70° + 2-5mm land | J-groove milling cutters | Pipe welding, nuclear equipment (prevents lack of fusion) | ASME BPVC Section IX |
| Chamfer | Symmetric small-angle edge (<30°) | 15°, 20°, 30° | Chamfer tools, deburring machines | Thread lead-ins, shaft assembly guidance | DIN 509 (Chamfer Dimensions) |
| Micro-Bevel | Ultra-narrow edge (<0.5mm width) | 10-25° | Precision grinding, EDM | Optical components, semiconductor wafer edges | SEMI Standards |
| Asymmetric Bevel | Uneven top/bottom angles | e.g., Top 30°+Bottom 45° | Custom tools, 5-axis machining | Aerospace composites, automotive panels | NADCAP (Special Processes) |
| V-Bevel | Equal double-angle “V” groove | 60°-90° | Plasma/Oxyfuel cutting | Structural steel welding, pipe butt joints | ISO 9692 (Weld Preps) |
| Undercut Bevel | Reverse angle (wider base than top) | 30° reverse taper | Tapered end mills, EDM | Mold draft angles, jewelry settings | Custom drawing callouts |
| Hollow Bevel | Concave curved edge | R>10mm | Contour milling, 3D printing post-process | Ergonomic product edges, high-end furniture | ASTM F1858 (Furniture) |
Machining Notes
-
Tool Selection: Carbide for steel, diamond for CFRP.
-
Cooling: Oil-cooling for titanium, air-cooling for aluminum.
-
Deburring: Electrochemical deburring for internal edges.
