What is the result of excessive vibration during machining?

Excessive vibration during machining has significant negative impacts, primarily leading to decreased part quality and reduced tool life. When vibration occurs, it can cause the cutting tool to deviate from its intended path, resulting in poor dimensional accuracy and surface finish of the machined part. This deviation can create inconsistent cuts and lead to defects such as chatter marks on the finished surface.

Additionally, excessive vibrations can increase wear on the tool, shortening its lifespan. The constant fluctuation stresses on the tool can lead to premature failure or breakage, necessitating more frequent tool replacement, which increases production costs and downtime. Overall, managing vibration is crucial in machining processes to maintain the quality of parts produced and to extend the life of tools used.
