| 摘 要： | 针对航空发动机常用材料钛合金TC17，采用白刚玉砂轮与微晶刚玉砂轮开展磨削试验，研究微晶刚玉砂轮对工件表面质量和磨削力大小的影响规律。试验结果表明:微晶刚玉砂轮磨削后工件表面质量更好，表面粗糙度值降低0.14 μm，磨削力降低10%左右。针对微晶刚玉砂轮进行磨削参数对磨削力影响规律的单因素试验，从磨削力角度分析微晶刚玉砂轮磨削钛合金的合理工艺参数。综合磨削力与加工效率因素，确定磨削钛合金TC17的合理参数为:砂轮线速度vs=27 m/s、磨削深度ap=0.01 mm、工件进给速度vw=12 m/min；对磨削力试验数据进行多元线性回归分析，建立了法向磨削力和切向磨削力的回归模型。

| Abstract: | Grinding experiments were conducted on titanium alloy TC17 with microcrystalline alumina and white alumina grinding wheels separately to study their grinding performance,such as surface quality and grinding force.The results show that surface ground by microcrystalline alumina has better quality,with surface roughness value decreased by 0.14 μm and grinding force decreased by 10%.Single factor tests were conducted to study the influence of grinding parameters on the grinding force of microcrystalline alumina wheels.It is found that the optimal parameters for grinding TC17 are linear speed of the wheel vs=27 m/s,grinding depth ap=0.01 mm and workpiece infeed rate vw=12m/min.In the end,multiple linear regression analysis is carried out on test data of grinding force,and the regression models of normal and tangential forces of grinding are established. |
