Abstract: Pointing to the real-time monitoring and control of small-circular vibration of the main vibration platform in graphite electrode abrading machine, the vibration of the main vibration-platform in X, Y axis is-detected by a eddy transducer with two probes. A neural network fitting method about calibration data of the transducer may guarantee the detecting accuracy. The small circular vibration dynamic amplitude of the main vibration amplitude on platform can be obtained through real-time vibration displacement measurement between the main vibration-platform and probes, and hence the machine is controlled to ensure the abrading process to be conducted smoothly, which could provide amplitude parameters for translation moving head in EDM process.
