Abstract Different aspects on the tool wear behavior of profiled vitrified microcrystalline alumina wheels during creep feed grinding of Ni alloy blade root were investigated. Experimental results indicate that the wheel peak regions had the higher wear values than the wheel valley regions by around 21.7%, 42.8%, 34.5%, in terms of the profile heights, circle radii and angles respectively. Furthermore, the wear flats, workpiece material adhesion, and the fractures of grains and bond bridges occurred in the wheel peak regions; while in the wheel valley regions, heavy wheel clogging, fractures of grains, and workpiece material adhesion were produced. Based on the experimental results, an analytical model with the average error of 17.3% to predict the wheel profile wear was finally developed.

陶瓷微晶氧化铝砂轮在单晶镍基高温合金涡轮叶片根部蠕变进给成型磨削中的刀具磨损行为

摘要 研究了异形陶瓷微晶氧化铝砂轮在镍合金叶根蠕动磨削过程中刀具磨损行为的不同方面。实验结果表明，在轮廓高度、圆半径和角度方面，车轮峰值区域的磨损值比车轮谷区域高约 21.7%、42.8%、34.5%。此外，磨平、工件材料粘附以及晶粒和键桥的断裂发生在轮峰区域；而在轮谷区域，则产生严重的车轮堵塞、晶粒破裂和工件材料粘附。基于实验结果，最终开发了一个平均误差为17.3%的分析模型来预测轮廓磨损。
