The Development Of Online Monitoring System Of Machine Tool Cutting Force Signal

It is necessary to monitor and control the manufacturing procedure during the course of working. Thus it can be safe and reliable to carry through the production .The research of the paper realizes real-time monitoring the process through computer collecting data and information.The thesis is a system of on-line monitoring the cutting force of numerical control machine, which implements using Visual C++. It concludes the collecting of data, real time monitoring and subsequent processing and analyzing of cutting force.In the part of signal acquisition, the system gets signal through piezoelectric sensor and real time collects it through programming the card of data acquisition, at the same time, displays the signal dynamic. So it can be monitoring the cutting force. In the part of signal processing, the system realizes processing and analyzing of signal. It includes showing, filtering, correlation and spectrum analyzing the signal so as to get the character of cutting force. In the end of the paper, the system is proved through monitoring the signal of turning force. Thus the system is use and reliable.
