摘　　要：为控制涡轮叶片榫齿表面粗糙度,基于实验研究磨削参数对定向凝固高温合金IC10缓进磨削表面粗糙度的影响规律。结果表明:在实验参数范围内,垂直于磨削方向表面粗糙度为0.40~1.68μm,沿磨削方向表面粗糙度为0.08~0.28μm;增大砂轮线速度而减小工件进给速度和磨削深度都能降低磨削表面轮廓峰起伏程度,使磨削表面坑洞缺陷密度和划擦痕迹明显程度降低。为获得更好的表面质量,推荐磨削参数为v_(s)=36 m/s,v_(w)=50 mm/min,a_(p)=0.1 mm。To control the surface roughness of tenon teeth of turbine blades,the effect of machining parameters on the roughness of directionally solidified superalloy IC10 in creep grinding was studied based on experiments.The results show that the surface roughness perpendicular to the grinding direction is 0.40~1.68μm within the range of experimental parameters,the surface roughness along the grinding direction is 0.08~0.28μm.Increasing the linear speed of the grinding wheel and decreasing the feed speed and grinding depth of the workpiece can reduce the undulation degree of the grinding surface profile peak,so that the density of the grinding surface pits and scratches can be significantly reduced.Grinding parameters of v_(s)=36 m/s,v_(w)=50 mm/min,a_(p)=0.1 mm are recommended for obtaining better surface quality.
