为研究细晶硬质合金刀具铣削TC4钛合金的磨损机理及特性，在切削速度为100 m/min的条件下采用涂层细晶硬质合金刀片进行了干式铣削钛合金试验。试验前通过SEM照片得到了试验用刀片材料的原始显微结构。通过铣削试验，得到了铣削TC4钛合金后刀片的磨损特点，分析了刀片的主要磨损机理，并得出了刀片的磨损曲线。结果表明：在100 m/min的切削速度下，涂层细晶硬质合金YBG202刀片的磨损，主要发生在后刀面，磨损位置接近刀尖圆弧；刀具的磨损形式主要以粘结磨损为主，且磨损速度较快。

In order to study wear mechanism and the characteristic of fine grain cemented carbide tool in milling TC4 titanium alloy, the tests of dry milling titanium alloy used coating fine grain cemented carbide blade was carried out under the condition of the cutting speed of 100 m/min. The original microstructure of blade material was obtained through the SEM photos before the experiment. Through the milling test, wear characteristics of the blade was obtained, the main wear mechanism of the blade was analyzed, and the blade wear curve was drawn. The results show that:at the speed of 100m/min, the blade wear of coating fine grain cemented carbide YBG202 mainly occurs in the flank face, and wear location close to corner of knife nose;Form of tool wear is mainly adhesion wear, and the wear is faster.
