How can vibration affect machining accuracy?

• A. It improves surface finish
• B. It stabilizes the cutting process
• C. It causes inaccuracies in dimensional tolerances
• D. It enhances tool life

Answer: (C)

Vibration can significantly impact machining accuracy by causing inaccuracies in dimensional tolerances. During the machining process, vibrations can originate from various sources, including the machine tool, the cutting tool, or the workpiece. These vibrations lead to fluctuating positions of the tool and workpiece, which can result in inconsistent cutting depths and tool engagement. This variation directly affects the precision of the machined part. For instance, if a tool vibrates while cutting, it can lead to an unintended reduction in material removal in one area while overcutting in another, ultimately causing the finished part to fall outside of specified tolerances. In industries where precision is crucial, such as aerospace or automotive, maintaining tight tolerances is essential for the performance and safety of components. Therefore, managing vibration is critical to ensuring accurate machining results.
