CNC Machine Tool Fault Diagnosis System For Software Development

In the machinery industry, numerical control machine tool production in all areas of common use. On the other hand, the function of numerical control machine tools becoming more complex, numerical control machine tool breakdown, ruled out a long time, difficult and relatively large amount of maintenance. In addition, numerical control machine tools related to mechanical, electrical, hydraulic, pneumatic and other fields, the relevant technical requirements of high, when the machine broke down, in time for fault diagnosis and rule out very difficult. How in the failure of CNC machine tools, rapid diagnosis and maintenance becomes very important.Domestic and foreign experts on the system so that the fault diagnosis technology breakthrough in the traditional method of fault diagnosis, knowledge and experience-based intelligent detection and diagnosis of attention and technology has been applied to a machine for maintenance, operators to help fault diagnosis Expert System came into being.Experts fault diagnosis system are stored in the field of expert knowledge and experience of knowledge engineers, operators can display unit, a simple man-machine dialogue to choose Fault, running through the reasoning process to determine the reasons for failure, experts in the field have been troubleshooting methods So that the general staff for operation and maintenance of the same fault can be made with the level of expert-level diagnostic conclusions for on-site technical maintenance staff to complete fast fault location and fault repair to help.In this paper, numerical control machine tool fault diagnosis expert system development and design. The use of fault tree analysis (FTA) the establishment of CNC machine tools failure of the main parts of the fault tree, through the establishment of failure Access database, using Visual Basic 6.0 to develop numerical control machine tool design fault diagnosis system for fault diagnosis and maintenance tools to help. CNC machine tool fault diagnosis system attractive interface, easy operation, failure to provide a different way of inquiry. Combine characteristics of the machine tool and the failure occurred, machine tool operators can help determine the cause of the malfunction and troubleshooting of high value applications.
