Selection Of Optimal Superfinishing Parameters 最佳超精加工参数的选择
发布日期: 1999-11-01
本文讨论了最佳超精加工条件的选择。在圆柱表面超精加工过程中,轴向振动的磨石被压在旋转的工件上。实验结果显示了接触压力、工艺运动学和粒度对超精加工行为的影响。在最佳接触压力下,去除率达到最大。应选择轴向振动频率与工件旋转频率的比值,以避免整数值和半数值,前者会导致较低的坯料去除率,后者会导致波瓣形成。更细的砂石可以提供更平滑的表面光洁度,但去除库存量较少。 因此,选择的粒度应仅足够细,以产生所需的表面粗糙度。
This paper is concerned with selection of optimal superfinishing conditions. During superfinishing of cylindrical surfaces, an axially oscillating abrasive stone is pressed against the rotating workpiece. Experimental results are presented which show the effect of contact pressure, process kinematics, and grit size on superfinishing behavior. An optimal contact pressure is found at which the removal rate is maximized. The ration of the axial oscillation frequency to the workpiece rotational frequency should be selected so as to avoid integer values, which result in low stock removal, and half values, which can lead to lobe formation. Finer grit stones provide smoother surface finishes but less stock removal. Therefore the grit size selected should be only fine enough to generate the required surface roughness.
