Chatter Suppression with Piezoelectric Film for Microstructure Surface Structuring

Micro-structure surface is widely used in optics and industry due to their excellent properties, such as optical properties, wear resistance, adhesion and lubricity. The current Micro-structure surface manufacturing is mainly ultra-precision cutting. In the process of Micro-structure surface manufacturing, excessive spindle speed or depth of cut may cause the generation of chatter. Regenerative chatter is one of the most important factors affecting the quality of machining. Chatter can cause great harm to the whole process, it can cause reduced surface quality, noise and tool wear. The study of regenerative chatter has become a focus in the current manufacturing industry. The process of cutting can be simplified to a two-dimensional mass spring damping system. In this paper, for the chatter in Microstructure surface manufacturing, the cutting model is established and a method for suppressing chatter by using piezoelectric film is proposed. And the vibration suppression effect of two different piezoelectric materials PZT-5H and PVDF have been compared.
