Chamfer and fillet are both commonly used design features with sharp edges. Designers are always confused by these edge features. Although they sound similar, they have different features and uses. This article will discuss the differences between chamfers and fillets and offer some advice on whether to choose between them.<\/p>\n\n\n\n
Chamfer is a slop formed by cutting a sharp edge at a certain angle. A common procedure is cutting a right-angle edge into a 45\u00b0 surface. Charmfering is commonly used to remove burrs caused by machining or to facilitate the connection and assembly of the parts. It is widely used in furniture, printing circuit boards, and more.<\/p>\n\n\n\n Chamfer edges have different angled slopes; common chamfer angles are 45 degrees and 65 degrees.<\/p>\n\n\n\n Fillet is the arc that creates a smooth transition between the sharp edges of two mating surfaces. Fillet has a radii; it can be either internal or external to the part. Fillets are added to reduce the stress concentration of the edge and extend the lifespan of the part.<\/p>\n\n\n\n Fillets can be divided into three types by their location: mitre fillet, concave fillet, and convex fillet.<\/p>\n\n\n\n Mitre fillet: Bevel the edges so that the two faces meet at an angle.<\/p>\n\n\n\n Concave fillet: Concave the corner of a shape to form an inward arc.<\/p>\n\n\n\n Convex fillet: Convex the corner of a shape to form an outward arc.<\/p>\n\n\n\n Fillets can be easy to confuse with the other edge features, such as chamfers and bevels. The main geometric difference is that fillets have arcs while others do not. In addition, some other key features make fillet different from chamfer.<\/p>\n\n\n\n Fillets have no obvious turning points and use a continuous arc to connect different surfaces. This arc is very soft and smooth. Chamfers usually have a straight line transition at a certain angle such as 45 degrees or 65 degrees. Chamfers have a clear direction and a clear bevel turning point between two surfaces.<\/p>\n\n\n\n They are both added to reduce stress concentration and improve load-bearing capacity on sharp corners. However, their effect can be varied. Chamfer has a higher stress concentration because it cannot effectively distribute the stress over a broader surface compared to fillets.<\/p>\n\n\n\n Fillets are easier to be coated than chamfers. This is because fillets blend gently and tangentially with adjacent faces, allowing the part to adhere to a thicker, more even coating than chamfered edges.<\/p>\n\n\n\n Whether it is a screw hole, locating hole, or locating pin, chamfering the edge of the hole or pin is a better choice.<\/p>\n\n\n\n<\/figure>\n\n\n\n
