Abstract
A prognostic and health management system for precision ball grinding machines includes: a detector connected to a first and a second grinding discs; and a central processing module including a determining unit, a historical data recording unit, a timing unit, and an alarm unit. The detector is connected to the determining unit, detects data of the two grinding discs, and sends the data to the determining unit, the determining unit compares data in the historical data recording unit to determine whether the first and second grinding discs are abnormal, if there is an abnormality, the alarm unit releases a warning signal, if the determining unit determines that there is no abnormality, the timing unit records a grinding time of the first and second grinding discs, and based on a comparison of the past records, the alarm unit releases a warning signal after a predetermined time has elapsed.
