The design of CNC lathe cutting force signal on-line monitoring

摘要

The main task is to study the CNC lathe cutting force signal on-line monitoring system design, it mainly includes the cutting force signal acquisition, real-time monitoring and subsequent processing and analysis. Cutting force signal acquisition is the use of Kistler piezoelectric sensor signal, converted into voltage signal, and through the data acquisition board, to convert analog signals into digital signals, input to the computer, the computer real-time monitoring of machining process. Signal processing is to the acquisition of signal processing and analysis, to obtain the correct dynamic cutting force signal, to verify the stability and reliability of the whole monitoring system.
