Abstract

A framework for diagnosing and characterizing the failure propagation of various components in a CNC (computer numerical control) machine tool using real-time knowledge-based simulation is discussed. The input data necessary for conducting simulation are obtained from a knowledge base structured using frames. Preventive maintenance and sudden failures are modeled. The implemented system provides an integrated environment for the maintenance supervisors to obtain early warnings about the expected failure times of different components and the stoppage time of the machine tool. The system also provides the capability of identifying the critical components susceptible to frequent failures
