磨削表面形貌及其加工工艺参数的关系

采用平面磨床在20钢、45钢、40Cr钢试件表面进行磨削加工,通过粗糙度测试仪测量加工试件表面形貌,采用表面形貌统计参数中的轮廓高度算术平均值Ra、微观不平度十点高度Rz、轮廓微观不平度的平均间距Sm、轮廓支承长度率tp对表面形貌进行评价,分析了表面形貌参数与磨削加工工艺参数、试件材料的关系。结果表明,磨削表面形貌与加工过程中的工艺参数密切相关。

Relationship on Surface Texture and Grinding Parameters

The 20,45 and 40Cr parts are grinded on plane grinder.The surface textures are measured by roughness tester.The profile height arithmetic mean Ra,the ten-point height of irregularities Rz,the mean spacing of the profile irregularities Sm,the profile bearing length ratio tp are used to value surface roughness.The relationships between surface roughness parameters on grinding parameters and pieces materials are studied.The results show that surface textures are closely related to grinding parameters.
