To provide a method of processing a tempered glass in a simple and appropriate manner while a degree of freedom of processing is secured.;Vibration of the processing device is controlled in a feedback fashion such that a vibration amplitude and a vibration frequency of the processing device approach to a target vibration amplitude and a target vibration frequency not to keep them in a range where a value of worsening the quality is generated. Further, a specified sample cycle of 0.3 msec or less in the feedback control is employed. |
