DEVELOPMENT OF A KNOWLEDGE-BASED EXPERT SYSTEM USED FOR ERROR DIAGNOSIS OF FANUC CONTROLLED CNC MILLING MACHINE

35745

In this study, a knowledge-based expert system has been developed for the diagnosis of computer numerically controlled(cnc) milling machine with fanuc 18ibm control unit. These machines are heavily used in mold making workshops. The developed system provides a very fast and cost-efficient fault diagnosis help to users by supplying rare expertise knowledge. By using this expertise knowledge, users will find the reason of a fault and repair the machine themselves like a domain expert. It is also predicted that this system will be used as a teaching material for the Error/Fault Diagnosis lessons at the faculties and vocational schools. The developed system called CNCEXP has been programmed in Delphi language, and Excel work sheets have been used as a knowledge base. Inference engine and knowledge base are separated from each other. Thus the main advantages of this separation is to simplify the development of an expert system in different domain by replacing knowledge stored in the knowledge base of the developed system. Knowledge base of the developed system can be update easily.
