为实现复杂、异形刀剪的端面磨削，提出了一种空间端面磨削多轴联动控制方法。根据端面磨削的工艺特点与卧式端面磨床的结构特点，建立了砂轮径向进给量、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了一个旋转轴与两个平动轴的三轴联动控制。基于所提控制方法开发了数控系统，该系统支持二维图形与参数混合编程。利用该系统开发了数控端面磨床样机，并进行了磨削实验。结果表明，该磨床能够磨削多种刀剪产品，加工效率与质量优于液压式端面磨床。

In order to realize the surface grinding of complicated and specially-shaped knives and scissors,a multi-axis motion control method is proposed for spatial surface grinding.Based on the characteristics of surface grinding and horizontal surface grinder,the functional relationship between machining parameters and process parameters is established.The machining parameters include radial feed,axial feed and rotation angle,and the process parame-ters includes grinding depth of top surface,grinding depth of bottom surface and grinding width.Then,the joint control of one rotational axis and two translational axes is realized by taking into account surface projection rules. Based on the proposed control method,a computer numerical control (CNC)system is developed,which supports the mixed 2D graphic and parametric user programming.Finally,the CNC system is employed to develop a proto-type of numerical control surface grinder,and grinding experiments are performed by using the surface grinder.The results show that the surface grinder is able to manufacture various kinds of knives and scissors and is superior to a hydraulic surface grinder in terms of efficiency and quality.
