Red Seal Machinist Practice Exam

What is a significant benefit of chamfering in machining?

1. It increases production speed

2. It simplifies assembly of components

3. It helps eliminate sharp edges, reducing risk of injury

4. It guarantees perfect finishes on all surfaces

The correct answer is: It helps eliminate sharp edges, reducing risk of injury

Chamfering involves creating a beveled edge on the workpiece, which plays a crucial role in enhancing safety by removing sharp edges. This reduction in sharpness not only lowers the risk of injury for operators handling the components but also prevents damage to other parts during assembly and use. In addition to safety concerns, chamfering can also facilitate the proper alignment and fitting of parts during assembly, but that is a secondary benefit compared to the primary objective of ensuring safety. While increasing production speed and guaranteeing perfect finishes are desirable in machining, they are not inherent advantages of chamfering. The main focus of chamfering is centered around improving safety and usability by addressing the potentially hazardous sharp edges.
