Abstract

In metal cutting processes, an effective monitoring system, based on a suitably developed scheme or set of algorithms can maintain machine tools in good condition and delay the occurrence of tool wear. In this paper, an approach is developed for fault detection based on a distributed system. Firstly, identifying of sensor instrumentation system is responsible for the signal processing and the system fault information. Secondly, the sensor wireless networks are used to transmit the data (lower layer) to or receive the commands from the computer center (top layer). Thirdly, the computer center at the top layer will monitor the overall system and generate the alarm signals or the commands when the faults occur.
