摘　　要：为提高球头弹性磨具磨削M330钢材的加工效率和磨削效果,采用#600球头磨具进行磨削M330钢材实验.通过设计正交实验,研究了不同磨削参数时M330试样的表面形貌和材料去除机理,并得到了初步优化参数.通过单因素实验进一步优化了工艺参数.实验结果表明:增大球头磨具直径、供液速度及减小进给速度,均能降低表面粗糙度;磨削后试样表面粗糙度随设定磨削深度的增加先减小后增加;采用的高速供液法能显著降低试样表面粗糙度,有效改善球头磨具表面的切屑黏附现象;采用高速供液后,可在保证磨削质量的前提下提高进给速度;主轴转速越高,对应最佳供液速度越高.实验得出的不同主轴转速下对应的最佳供液速度为使用MOORE-450CPW连续轨迹坐标磨床进行的磨削加工提供了参照依据.To improve machining efficiency and grinding effect of flexible abrasive grinding of M330 steel, grinding experiments were conducted using #600 ball-end flexible abrasive. Through orthogonal ex- periment design, surface morphology and material removal mechanism of M330 samples with different grinding parameters were studied, and preliminary optimization of parameters was obtained. With single factor experiment, the process parameters were further optimized. Experimental results show that increas- ing flexible abrasive diameter and jet velocity and decreasing feed speed can reduce the surface rough- ness. After grinding, the surface roughness of the specimen first decreased with the increase of setting grinding depth and then increased. High speed fluid injection can reduce the surface roughness of the specimen significantly and improve the chip adhesion phenomenon of flexible abrasive surface effectively. After adopting high speed fluid injection, the feed speed can be improved under the premise of grinding quality. The higher the spindle speed, the higher the corresponding optimum jet velocity. Corresponding optimum jet velocity of different spindle speeds obtained in experiments provides reference for grinding machining using MOORE-450CPW continuous trajectory coordinates grinder.
