摘要
采用CALISUM表面粗糙度仪、显微硬度仪及X射线应力衍射仪对GH4079高温合金磨削表面特征（表面粗糙度、表面显微硬度及表面残余应力）进行测定,研究在砂轮线速度范围为15-25 m/s,径向进给量范围为0.05-0.15 mm,工件速度范围为40-80 mm/min的切削用量下,GH4079高温合金的表面特征。同时揭示了表面特征参数随磨削用量的变化规律,为GH4079高温合金磨削加工参数的选择提供实验基础依据。
CALISUM surface roughness tester, hardness tester and X - ray diffraction stress were used to measure grinding surface characteristics （surface roughness, surface hardness and surface residual stress） of GH4079 superalloy, where wheel speed in the range of 15 -25m/min, grinding depth in the range of 0.05 -0.15mm, feedspeed in the range of 40 -80mm/min, the grinding surface features was investigated, at the same time shows that the characteristic parameters of grinding changing with the dosage of grinding, an experimental basis was provided for selecting grinding parameters of GH4079 superalloy.
