钛合金具有比强度高和耐腐蚀性能好等突出的优越性能,已成为当前航天航空工业中的重要材料,而且在造船、化工、冶金、医疗和生活用品等民用工业方面也获得了广泛的应用。但是,由于钛合金的切削加工性差、刀具磨损严重和加工时易产生振动等原因,妨碍了其加工生产率和质量的提高。我们在加工钛合 Titanium alloy has prominent advantages such as high specific strength and good corrosion resistance. It has become an important material in the aerospace industry and has also been widely used in civil industry such as shipbuilding, chemical industry, metallurgy, medical treatment and daily necessities . However, due to the poor machinability of the titanium alloy, the serious wear and tear of the tool and vibration during processing, etc., the processing productivity and quality of the titanium alloy are hindered. We are processing titanium
