This invention discloses a grinding wheel dressing method for machining cycloidal gears using a worm gear grinding machine. The key feature is the use of a worm gear grinding machine that integrates cycloidal gear machining and grinding wheel dressing functions to achieve rapid and precise grinding wheel dressing. The worm gear grinding machine, with an adjustable central axis swivel angle for the dresser, increases the dresser's freedom of movement during dressing, reducing the impact of changes in the grinding wheel tooth profile, controlling errors during dressing, and improving machine tool stability. A contact vibration sensor is installed on the grinding wheel; by sensing vibration data, the machine tool automatically adjusts the dresser's alignment, simplifying manual operation, improving dressing accuracy, and saving time. After the initial alignment, the dresser does not need to be aligned again, improving dressing efficiency. By differentiating the two-stage machining process of dressing the grinding wheel, the roughing stage quickly removes excess material from the grinding wheel while the finishing stage maintains a good surface morphology.
