摘　　要：针对齿轮类零件的成形磨削,研制了一种成形砂轮的新型数控修整系统。系统选用金刚石修整轮作为修整工具,在软件算法中设置特殊的修整参数,依据曲面啮合原理计算目标工件磨削所需的砂轮截形,利用数控修整系统进行砂轮的自动修整。选取一种生产中的修缘蜗杆进行磨削和修整实验,检测蜗杆齿形的精度达到6级以上,证明了该修整系统的实用性。To aim the forming grinding of gears parts, a new Computerized Numerical Control （CNC） of grinding wheel dressing is developed. The calculation of the section profile of grinding wheel, for the grinding of gears parts, is achieved by surface meshing theory, based on the software arithmetic with special parameters. With diamond dressing wheel, the grinding wheel is auto-trimming by CNC dressing system. As the proceeding of the grinding and dressing experiment of a practical worm the accuracy of the worm tooth shape reaches level 6 and above, satisfying the practical applicability of the dressing system.
