Vibration Control

Definition

Vibration control refers to the techniques and methods used to minimize or eliminate unwanted vibrations in mechanical systems. This is particularly crucial in machining and drilling processes, as vibrations can lead to poor surface finish, reduced dimensional accuracy, and increased wear on tools. Effective vibration control ensures stability and precision in manufacturing operations, ultimately enhancing product quality and operational efficiency.
