Development of Processing Monitoring and Signal Processing System for NC Machining |
| |
| Abstract: | A Machining monitoring system based on immune theory is designed in this paper in order to control the NC Machining. The design of software in LabVIEW and hardware for condition monitoring is presented. The multi-signals processing methods including power spectrum analysis, Negative-Selection Algorithm based on immune mechanism and Genetic Algorithm are applied to monitor machining precisely in time. It has been proved from experiments that, with great flexibility and expansibility, this monitoring system will have a significant sense on avoiding and reducing the fault of NC initiatively. |
