Preliminary Research on the Measurement of Oxide Layer of ELID Based on the Laser Sensor and the Eddy Current Sensor

Abstract

In order to measure thickness and Study on growth behaviors of oxide layers on grinding wheel surface in ELID, the measurement system consisted of a laser sensor and an eddy current sensor was constructed to do a preliminary research on oxide layer replaced by rust. Through the comparison of the values of the thickness obtained by measurement system and the electron microscope of high precision, in this paper, the accuracy of the measurement result and the feasibility of the system ware verified.
