摘　　要：针对涂层材料改善刀具切削性能这一问题,本文采用常速试验和高速试验的方法,对比分析了七种涂层材料对铣刀切削性能的改善程度。试验结果表明:涂层性能优越与否与切削速度有很大关系,AlCrN和TiAlCN涂层铣刀更适合高速切削;而AlTiN涂层铣刀不适合高速切削;TiN涂层铣刀无论在常速和高速切削时性能均表现不佳,高速切削时磨损相对更快;CrN+TiN复合涂层抗氧化能力较好,但抗磨能力相对较差。Based on the problem that coatings can improve performance of cutting tool,common speed experiment and high speed experiment were done in this article to compare and analyze the improvement of milling cutters＇ performance by seven types of coatings.The results demonstrated that coating performance had a good relationship with cutting speed.The milling cutters with AlCrN and TiAlCN coatings were more suitable for high speed machining.Instead,the milling cutter with AlTiN coating was not suitable for high speed machining.The milling cutter with TiN coating did not show a good cutting performance both in common speed and high speed,especially in high speed machining.CrN＋TiN multi-coating had a good antioxidant capacity,but the antiwear property was relatively bad.
