Kurzbeschreibung/Abstract
The main objective of DIAMOND ("Diagnosis and Monitoring for Machine Tools, Integrated in Advanced CNC's") is to increase the ability of the machine tool operators to identify and repair most of the faults in their machines. To accomplish with this objective we must consider:
The development of inexpensive and configurable monitoring modules.
To engineer diagnosis tools that employs all the sources of information available and learn from past experiences.
The fully integration of these tools in the CNC of the machine.
To provide repairing instructions to the operator by means of annotated CAD drawings, video, etc.
A methodology to select sensors, to parameterize the monitoring modules and to compile diagnosis data.
Information needed for the successful diagnosis of typical machine failures must first be acquired with a monitoring software tool capable of supporting various types of sensors. This tool should deliver the maximum amount of information with the minimum number of external low cost sensors. It benefits from the new capabilities of open CNCs with standard hardware like an integrated PC offer.
Starting from these monitoring data, and in close relation with the machine operator, the next step provides a diagnosis about the actual problem. The troubleshooting system employs explicit information (expressed as rules and fault trees) and previous experiences (by means of Case-based Reasoning) to find out the most probable causes.
Once the failure is identified, the last step is to provide repairing instructions to the machine tool operator. Multimedia tools, integrated in the CNC of the machine, are provided to accomplish with this goal.
As ultimate resort, an enhanced telephonic link permits to connect the technical assistance service of the machine tool builder with the advanced CNC, allowing the collaboration between the machine operator and the expert technician to solve the most complex situations.
