The present paper addresses systematic approach to Condition-Based Maintenance, and research results at the University of South Carolina Condition-Based Maintenance Research Center, directly related to U.S. Army rotorcraft Vibration Management Enhancement Program. The paper gives an analysis of the CBM concept and its functional layers, such as condition monitoring, diagnostics, prognostics and...

Abstract Effective monitoring of the tool wear condition within a machining process can be very challenging. Depending on sensors used, often only part relevant information detected. In case milling processes data acquisition is made even more difficult by fact that working point inaccessible for sensor applications due to physical tool, itself, chipping and used cooling-lubricants. By using va...
