| 摘 要： | 对硬质合金整体立铣刀高速铣削加工航空铝合金时的刀具磨损形态及其磨损机理进行了观察和分析.结果表明:在高速切削条件下,硬质合金整体立铣刀的磨损形态主要表现为涂层破坏、月牙洼磨损、微崩刃、剥落和破损等.磨损机理主要是粘结磨损、扩散磨损以及疲劳磨损.与常速铣削磨损机理的不同之处在于高速旋转形成的热、力耦合的应力场对硬质合金刀具的作用与冲击影响占主导地位.

| Abstract: | The wear patterns and wear mechanisms of solid cemented carbide are analyzed in high-speed milling of aluminum alloy. Results show that the dominant wear patterns are coating damage, crater wear, micro-chipping, breakage, and so on. The main wear mechanisms are adhesion, diffusion and fatigue. Compared with conventional speed machining, the effect and impact of thermal-dynamical coupling field play an important role in the cutting tool wear in high-speed milling of aluminum alloy. |
