What is the primary purpose of chamfering in machining?

• A. To increase part strength
• B. To improve surface finish
• C. To remove burrs and aid in assembly
• D. To enhance aesthetic appearance

Answer: (C)

Chamfering primarily serves the function of removing burrs and aiding in assembly. When metal parts are machined, they can develop sharp edges and burrs that may interfere with assembly or pose a safety hazard. Chamfering creates a beveled edge at a specific angle, effectively eliminating these sharp edges and burrs. This process not only makes it safer to handle the parts but also simplifies the assembly process by allowing components to fit together more easily. While other options may describe potential benefits or secondary effects of chamfering, such as enhancing appearance or possibly contributing to surface finish, the main and most critical purpose in a machining context is to facilitate easier assembly and to ensure that parts can be safely handled.
