12 Ways To Reduce Cutting Vibrations On Cnc

In the milling of thin-walled workpieces, the cause of the vibration is entirely from the workpiece, which is called a box or bowl part. Since the vibration comes from the workpiece itself, the main focus when dealing with the milling of such parts is to improve the clamping of the workpiece.

State-of-the-art review on vibration-assisted

05.05.2018  Vibration-assisted machining (VAM) is an external energy assisted machining method to improve the material removal process by superimposing high frequency and small amplitude vibration onto tool or workpiece motion. VAM has been applied to several machining processes, including turning, drilling, grinding, and more recently milling, for the processing of hard-to-machine materials.
