Method and devices for the rapid and flexible dressing of grinding worms

Disclosed is a method for dressing a single- or multi-thread grinding worm (34) in which a main rolling movement between the grinding worm and a gear-like dressing tool (90) is brought about. In order to create flank modifications on the grinding worm, an additional relative movement is superimposed on the main rolling movement. In addition, an auxiliary drive specifically designed for such a method, a correspondingly designed machine tool and a dressing tool for carrying out the method are disclosed. 公开种用于修整单线的或多线的蜗杆磨削轮(34)的方法，其中在蜗杆磨削轮和齿轮状的修整工具(90)之间产生基本展成运动。为了在蜗杆磨削轮上产生侧壁改型部，将附加的相对运动与基本展成运动叠加。此外，公开种专门针对这种方法配置的附加驱动器、种相应配置的机床和种用于执行所述方法的修整工具。
