“…These waves are called acoustic emissions. Today, the acoustic emission technique is widely applied for material testing and structural health monitoring on engineering materials such as concrete [2][3][4], metal alloys [5] and fiber composite materials [6]. However, the oldest reported scientifically planned acoustic emission experiment avant la lettre was performed on wood in 1933 by Fuyuhiko Kishinouye [3,7,8], long before the term acoustic emission (AE) was introduced by Schofield in 1961 [3].…”

Acoustic emissions are frequently used in material sciences and engineering applications for structural health monitoring. It is known that plants also emit acoustic emissions, and their application in plant sciences is rapidly increasing, especially to investigate drought-induced plant stress. Vulnerability to drought-induced cavitation is a key trait of plant water relations, and contains valuable information about how plants may cope with drought stress. There is, however, no consensus in literature about how this is best measured. Here, we discuss detection of acoustic emissions as a measure for drought-induced cavitation. Past research and the current state of the art are reviewed. We also discuss how the acoustic emission technique can help solve some of the main issues regarding quantification of the degree of cavitation, and how it can contribute to our knowledge about plant behavior during drought stress. So far, crossbreeding in the field of material sciences proved very successful, and we therefore recommend continuing in this direction in future research.

“…Acoustic emission technique (AET) has been used for monitoring different forming and machining processes (Dornfeld and Kannatey-Asibu, 1980;Nakao Yohichi and Dornfeld, 2003;Axinte Dragos et al, 2005;Jayakumar et al, 2005). During machining, acoustic emission is generated from (i) primary deformation zone ahead of the cutting tool where the initial shearing occurs during chip formation, (ii) secondary deformation zone along the chip-tool-rake face interface where sliding and bulk deformation occur, and (iii) tertiary deformation zone along the tool flankworkpiece interface (Dornfeld and Kannatey-Asibu, 1980).…”

“…These research results verified that it is feasible to develop a monitoring method for material removal during grinding based on the force sensor signal. However, a means of directly measuring the grinding force has yet to be developed due to the difficulty of installing the measuring instrument at the point of internal plunge grinding [10] . Recently, Chen Jiang et al [11] reported an acoustic emission (AE) model based on grinding force models for the prediction of material removal from a workpiece.…”

“…These findings demonstrate that the monitoring of material removal in plunge grinding is feasible for analysing and controlling the grinding quality. The main drawback of AE signals is the sensitivity variation according to the mounting position of the AE sensor [10] . Hence, it is impossible to mount the AE sensor at the same point for all machine tools to obtain the same sensitivity.…”

In production engineering, monitoring of the grinding process is critical for acquiring information on material removal, wheel performance, and workpiece quality. Here, a general model of the power signal and material removal rate is proposed to monitor the internal plunge grinding of a bearing outer race way product. Three continuous grinding cycles after dressing were used to analyse the roughing, semi-finishing, finishing and spark-out process under the same parameters.Based on the actual grinding process, a practical analysis method is applied to improve the general model to predict more accurately the power curve. Finally, estimations of grinding wheel performance and grind quality using the grinding power signal model (GPSM) coefficients are also presented. The experimental results showed that the improved power signal model is capable of solving the industrial problem of multi-stage in-feed grinding cycles and improving grind quality.
