【 摘 要 】

Sustainable development for machining strategies, process, and technologies, is compulsory in the industries. Machining surface quality improvement and the extension of tool life-time are commonly set as goals by many researchers, in the fulfilment of that sustainable development. Unforeseen and uncontrollable vibration or known as passive vibration is an unavoidable effect and a menace in machining. However in contrary, adding active vibration with stable frequency and amplitude, and small depth of cut during machining, give positive impact toward machine performance and surface quality. Vibration Assisted Machining (VAM) generates active vibration on the tool or workpiece. That vibration repeatedly causes tool-workpiece separation for a period of time during machining. The tool-workpiece separation is the main reason of VAM advancements. Adding VAM to conventional machining requires further consideration in term of design and cutting method, which are investigated in this comprehensive literature review. Critical aspect in adding VAM to micro milling machine was also discussed.
