摘　　要：针对阿基米德蜗杆(ZA型蜗杆)磨削加工的要求,建立了阿基米德蜗杆磨削加工的数学模型,根据CNC砂轮修整器的成形原理,推导了磨削用砂轮截形的计算方法,利用MATLAB计算得到砂轮回转面的截形,在带有CNC砂轮修整器的数控螺纹磨床上实现了蜗杆的磨削试验。试验证明,该方法稳定提升了蜗杆的磨削精度,而且操作简单。Considering the requirements of grinding machining of archimedes worm （ ZA-worm）, mathematical model of processing archimedes worms has been established. The grinding wheel section equa- tion has been deduced based on the form grinding principle of CNC （computerized numerical control）. Grinding wheel dresser and the grinding wheel＇s revolution surface has been calculated by MATLAB pro- grams. In the paper, the experiment has been done on a grinder with a CNC grinding wheel dresser. It shows that the accuracy is improved and operation is easier by using the method.
