Generalized reliability growth in CNC system development (3)
(6) Perform error proof design. Misuse and misuse may occur from the design. (7) Perform ergonomic design. Ensure adequate maintenance space during maintenance, with sufficient brightness, low vibration and noise. (8) Design the maintainability of the software. It is convenient to recover and modify lost programs and data. (9) Conduct a diagnostic design. Set up various diagnostic programs to prevent the occurrence and expansion of faults. After the fault is issued, the type and location of the fault can be quickly identified. (10) Design the monitoring function. It can monitor the status of the CNC system and alarm the abnormality of the CNC system to provide information for fault diagnosis. For example, in the GICC system, a reset function is designed to improve maintainability. In the event of a downtime caused by an interrupted operation due to program and data processing, the reset button can be pressed to put the control system into a normal working state. This will not destroy the software and normal interrogation results. 3 Conclusion The generalized reliability growth in the development of numerical control systems is not only the reliability growth but also the maintenance improvement. The growth of generalized reliability should be achieved by the most economical means. Previous page
(5) Design to improve maintenance efficiency. Try to use components or components that can be quickly assembled and disassembled; perform proper structural design so that no parts or components are removed or removed when repairing a part.
