| 摘 要： | 为解决整体叶轮扭曲叶片型面的精加工难题,本文进行了五轴联动数控展成电解磨削的基础研究.在分析平行直纹展成电解磨削整体叶轮扭曲叶片的过切误差、得到过切误差计算公式的基础上,提出用圆锥磨轮和组合式五轴联动数控方案来消除过切误差的方法.文中还介绍了数控展成电解磨床的结构与运动、经济型多轴数控系统及其联动控制方法,并建立了电解磨削非平行直纹展成曲面的数学模型,开发了五轴联动数控展成电解磨削自动数控编程系统,对航空发动机整体叶轮的叶片型面进行电解磨削.结果表明,加工效率比手工修磨、抛光提高了12倍以上.

| Abstract: | To solve the problem of finishing the twist blade surface of an impeller, the five-axis numerically controlled electrochemical contour evolution grinding (NC-ECCEG) is studied. Over-cutting errors of NC-ECCEG of the twist blade surface generated by parallel lines are analyzed. The formula for calculating the over-cutting error is deduced. The method for eliminating the over-cutting error is used in the conical grinding wheel and the combined five-axis linkage NC-ECCEG system. The structure and the movement of the NC-ECCEG machine tool,the combined multi-axis NC system and its linkage control technology are introduced. Further, the mathematical model of the NC-ECCEG unparallel-ruled surface is established. An auto-programming system on five-axis NGECCEG is developed to grind the impeller. The machining efficiency of NC-ECCEG increases more than 12 times than that of manual polishing operations. |
