Prognostic and health management system for precision ball grinding machines

A prognostic and health management system for precision ball grinding machines, suitable for application to a first grinding disc and a second grinding disc of the precision ball grinding machines, the prognostic and health management system comprising:

• a detector connected to the first grinding disc and the second grinding disc;
• a central processing module including a determining unit, a historical data recording unit, a timing unit, and an alarm unit, the detector being signally connected to the determining unit, the detector detecting data of the first grinding disc and the second grinding disc from beginning to damage and sending the data to the determining unit, the determining unit comparing past records stored in the historical data recording unit to determine whether the first grinding disc and the second grinding disc are abnormal, if there is an abnormality, the determining unit drives the alarm unit to release a warning signal, if after the determining unit compares the past records stored in the historical data recording unit, determines that there is no abnormality, the timing unit records a grinding time of the first grinding disc and the second grinding disc, and based on a comparison of the past records stored in the historical data recording unit, the determining unit drives the alarm unit to release a warning signal after a predetermined time has elapsed.
