Cutting vibration usually occurs in turning of slender shafts, turning of thin-walled parts, and so on. When vibration becomes intense, severe vibration of more than dozens of amplitude μm occurs usually accompanied by loud noise. In cutting, vibration may exceed 100μm, and machining is possible, but it leaves visible vibration scratches on the machined surface, which is not allowed on the finishing surface.

Vibration generated by metal cutting processing is a bad phenomenon:

1. Affect the surface quality of parts: If vibration is generated in the processing, the relative displacement between the tool and the workpiece, vibration marks on the machined surface, seriously affecting the surface quality of parts and performance

2. Reduce the life of machine tools and tools: cutting vibration, the process system is continuously subjected to dynamic alternating loads, the tool is easy to wear (or even knife crash), the connection characteristics of the machine tool is destroyed, and in severe cases, it can not continue to cut processing

3. Noise damage to the operator's health: The noise generated by vibration can also damage the operator's health. In order to minimize vibration, it is sometimes necessary to reduce the amount of cutting, reducing the production rate of machine tool machining. Therefore, the control of cutting vibration is becoming increasingly important in order to determine the proper functioning of such machining equipment.
