[0060] When the grinding wheel is passivated, the grinding wheel dressing component is controlled to perform grinding and shaping on the grinding wheel according to the shaping parameters set by the human-machine interface.

[0061] The grinding wheel dressing assembly comprises: a grinding wheel dressing pen 1 (such as a diamond pen), an X-axis driving assembly 2 and a Y-axis driving assembly 3.

[0076] Step S101: The grinding wheel spindle current detector detects the real-time working current of the grinding wheel spindle and sends it to the shaping controller;

[0077] Step S102: the shaping controller determines the passivation condition of the grinding wheel according to the real-time working current of the grinding wheel spindle;

During the grinding process, the wear of the grinding wheel is judged by detecting the current change of the grinding wheel spindle. When the spindle current changes to a certain proportion, it is determined that the grinding wheel is passivated and the grinding work is automatically stopped. The grinding wheel grinding component re-grinds the grinding wheel and calculates the diameter of the grinding wheel after grinding. Then, according to the grinding wheel diameter and the position of the feed shaft before the grinding wheel is ground, the new working starting point position of the grinding wheel feed shaft is calculated, and then the grinding wheel feed shaft is controlled to move to this position to continue the grinding work.
