定向凝固高温合金IC10缓进磨削表面粗糙度研究
Study on Surface Roughness of Directionally Solidified Superalloy IC10 in Creep Grinding
摘要
Abstract
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 0.40～1.68 μm within the range of experimental parameters,the surface roughness along the grinding direction is 0.08～0.28 μm.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 vs=36m/s,vw=50 mm/min,ap=0.1 mm are recommended for obtaining better surface quality.关键词
