Review of chatter in micro and macro cutting operations machining biomaterials
Chatter presents one of the main problems in quality of machined surfaces limiting tool life, productivity and tolerances. Chatter in milling and turning operations has been extensively analysed however, drilling operations have been neglected due to the complexity of drilling tools and problems that develop in the modelling of the tool. In this paper, an overview of chatter vibrations and chatter suppression in drilling has been presented. In addition, the problem of chatter analysis and suppression in micromachining processes has been investigated. The differences in macro and micro scale problems have been addressed giving an overview of the current research directions and future work for both areas.
