【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.
[Abstract]:In order to improve the efficiency and effect of grinding M330 steel with ball-head elastic grinder, the experiment of grinding M330 steel with # 600 ball-head grinder was carried out. The surface morphology and material removal mechanism of M330 samples with different grinding parameters were studied by orthogonal experiments, and the optimized parameters were obtained. The process parameters were further optimized by single factor experiment. The experimental results show that the surface roughness can be reduced by increasing the diameter of ball-head grinder, the feeding speed and decreasing the feed speed, and the surface roughness decreases first and then increases with the increase of grinding depth after grinding, and the experimental results show that the surface roughness of the specimen decreases first and then increases with the increase of grinding depth. The high-speed fluid-supplying method can significantly reduce the surface roughness of the specimen and effectively improve the chip adhesion on the surface of the ball-head grinder, and the feed speed can be improved on the premise of ensuring the grinding quality by adopting the high-speed liquid-supplying method. The higher the spindle speed is, the higher the optimal liquid supply speed is. The optimum velocity of fluid supply obtained from the experiments at different spindle speeds provides a reference for grinding with MOORE-450CPW continuous trajectory coordinate grinding machine.
