【摘要】：为实现复杂、异形刀剪的端面磨削,提出一种空间端面磨削三轴联动控制方法。根据端面磨削的工艺特点与卧式端面磨床的结构特点,建立砂轮径向进给量、轴向进给量、旋转角度等加工参数与工件顶面磨削量、底面磨削量、磨削宽度等工艺参数间的函数关系,并结合端面的投影规律,实现一个旋转轴与两个平动轴的三轴联动控制。建立砂轮轴向进给误差与砂轮直径、刃线轮廓以及旋转角度间的函数关系,并提出误差补偿方法。试验结果表明,所提运动控制与误差补偿方法能够实现复杂、异形刀剪的端面磨削。
[Abstract]:In order to realize the end surface grinding of complex and special-shaped cutter, a three axis linkage control method for spatial end surface grinding is proposed.According to the technological characteristics of the end surface grinding and the structural characteristics of the horizontal end grinding machine, the machining parameters such as radial feed, axial feed and rotation angle of the grinding wheel and the grinding amount of the top surface of the workpiece and the grinding quantity of the bottom surface are established.The functional relationship between grinding width and other technological parameters and the projection law of the end face are combined to realize the triaxial linkage control between one rotation shaft and two horizontal axes.The functional relationship between the axial feed error of the grinding wheel and the diameter of the grinding wheel, the contour of the edge line and the rotation angle is established, and the error compensation method is proposed.The experimental results show that the proposed method of motion control and error compensation can realize the end surface grinding of special-shaped cutter and shears.
