The motorized spindles play an important role in
high precision and high speed metal cutting, and increase
productivity benefit in die and mode, medical, and aerospace
industries. As a result, improper high speed operation of
bearings and system causes lower reliability. Lot of technology
and sensors are development to monitor the failure of
improper operation of motorized spindle. In this paper, one
piezo-electric force sensor is developed. And, One Class SVM is
investigated to monitoring and detects the unbalanced tool
operation. The result shows the monitoring system is validated
successfully
