摘要：
Titanium alloys have been widely used in aerospace, marine and medical industries, due to their high strength, good corrosion resistance and excellent heat resistance. High tool wear rate and low machining accuracy limits conventional micro-milling to meet increasing stringent demand. In this paper, a prototype of two-directional vibration stage and its control system are developed for non-resonant mode vibration-assisted micro-milling system. A series of slot milling experiments are carried out to investigate the effects of vibration parameters on burr generation. The results show that vibration-assisted micro-milling is an effective way to reduce burr size when choosing appropriate vibration parameters and directions.
