摘要/Abstract

摘要： 采用AlCrN涂层整体硬质合金立铣刀铣削TC4钛合金，测量周刃磨损量、切削力和切削振动。使用扫描电镜（SEM）观察刀具磨损形貌，应用能谱分析的方法研究刀具失效表面元素的分布规律。在揭示磨损机理的基础上，进一步探讨刀具磨损对切削力、切削振动的影响规律，为实现钛合金加工刀具磨损状态的在线检查提供理论和技术支持。研究表明：前刀面主要出现机械裂纹、热裂纹、粘结磨损和氧化磨损，后刀面出现机械裂纹、粘结磨损和氧化磨损；整体上，切削力和振动随着磨损量的增大而增大，但不同磨损状态对切削力和振动的影响不同。

Abstract: Experiments of milling TC4 titanium alloys with solid cemented carbide milling cutters coated with AlCrN are carried out. The tool wear of circumferential cutting edge, cutting force and vibration are measured. The tool wear morphology is observed by using scanning electron microscope ( SEM) , and the element distribution of the worn tool surface is detected by using energy dispersive spectrometer (EDS). The influence of tool wear on cutting force and vibration is further discussed based on the wear mechanism in order to provide a theoretical and technical support for the realization of online check of tool wear state. The experimental results indicate that the mechanical crack, thermal crack, adhesion and oxidation wear exist on the rake face, and the mechanical crack, adhesion and oxidation exist on the flank face. The cutting force and vibration increase with wear loss. The different states of wear have the different effects on cutting force and vibration.
