Abstract

As a different approach to most acoustic emission (AE) research in grinding, this paper focus on analyzing the raw AE signal instead of root-mean-square signal (RMS). Transitional characteristics of the raw AE signal during wheel/workpiece contact in a variety of grinding processes are discussed. Frequency analysis of the raw AE signal is carried out based on knowing the frequency response of the sensor employed. An assessment of the AE RMS technique with different integration time constants is conducted in order to determine appropriate ones for future production applications.
