An online monitoring, diagnosis and control system for heavy duty NC machine tool

摘要：

During machining some ultra-intense and specialshaped parts, unstability and surface ablation often turn up. Some large and heavy parts are often machined with heavy duty NC machine tool. For avoiding the processing defects of the above parts, an online monitoring, diagnosis and control system is designed for heavy duty NC machine tool. The system can online monitor the operation condition of heavy duty NC machine tool and real-time control the processing. Some methods of signal analysis and processing are adopted such as spectrum analysis, wavelet analysis, Wigner-Ville distribution and Artificial Neural Network etc. The system is developed with C language and Qt based on Linux operation system. Optical fiber communication is adopted between industrial computer and NC system. Experiment platform of the system is machining an aircraft landing gear with five-axis NC machine tool. The scheme is verified feasible after preliminary test.
