“…Figures 6 and 7 show waveforms and frequency characteristics of two typical types of AE events which were detected during the cyclic compression test of the ceramic fiber mat. The sources of these waveforms can be considered to be related to the shape of waveforms; 6) the burst type waveform with 600 kHz peak frequency is thought to be due to breakage of fibers and the continuous type waveform with 200 kHz peak frequency is due to friction of fibers, respectively. These frequency characteristics are reasonable because it is well known that the frequency of the AE signal has positive correlation with the formation time of the event.…”

“…This new system was named ''Continuous Wave Memory'' (CWM) and enabled continuous recording of AE waveforms with 10 MHz sampling frequency to hard disks for several hours. Short time Fourier transform (STFT) 5) was adopted as a method for direct handling of continuous AE waveforms and gave the time-frequency-magnitude characteristic of the continuous AE waveforms as useful information for classification of degradation 6) of the ceramic fiber mat. Figure 1 7) The data recording rate is 20 MB/s/ch, therefore the maximum recording time is 1.7 hours for 4 ch or 6.9 hours for 1 ch in the current hard disk with a capacity of 500 GB.…”

Waveforms of acoustic emission (AE) events come close and sometimes overlap each other when AE activity is very high. Conventional AE measurement systems which handle discrete AE events are not suitable for this situation because miss-detection of AE event occurs frequently. A new AE measurement system named as Continuous Wave Memory (CWM) was developed to solve this problem by recording the AE waveforms continuously to hard disks for several hours throughout the testing time. This new system enabled multiple analysis of one waveform with different filtering parameters. Short time Fourier transform (STFT) gave the time-frequency-magnitude characteristic of continuous AE waveforms and useful information for evaluation of degradation of materials. In this study, the degradation of ceramic fiber mat during cyclic compression test and the effect of binder-addition were evaluated by this new system. STFT results clearly showed the classification of degradation of the mat; breakage of fibers was the main source in the early compression cycles and sporadic friction between fibers became the main source of AE in the later compression cycles. The effect of organic binder to prevent the degradation of the mat was also estimated. It was observed that the friction signal disappeared and the breakage signal weakened in the binder-added specimens.

“…A number of different techniques are often used to evaluate tool wear, irrespective of the surface treatment or coating used, for example optical methods [8,9], acoustic emission detection [10][11][12], ultrasonic testing [13,14], and thermal/infrared measurements [15,16]. The cost and characteristics of each technique should be considered in order to ensure the best fit for a given monitoring purpose and application.…”

Coated high-speed steel tools are widely used in machining processes as they offer an excellent tool life to cost ratio, but they quickly need replacing once the coated layer is worn away. It would be therefore useful to be able to measure the tool life remaining non-destructively and cheaply. To achieve this, the work presented here aims to measure the thickness of the coated layer of high-speed cutting tools by using Barkhausen noise (BHN) techniques. Coated highspeed steel specimens coated with two different materials (chromium nitride (CrN), titanium nitride (TiN)) were tested using a cost-effective measuring system developed for this study. Sensory features were extracted from the signal received from a pick-up coil and the signal features, Root mean square, peak count, and signal energy, were successfully correlated with the thickness of the coating layer on high-speed steel (HSS) specimens. The results suggest that the Barkhausen noise measuring system developed in this study can successfully indicate the different thickness of the coating layer on CrN/TiN coated HSS specimens.

“…Although FT is one of the most recognised methods in signal analysis, it does not possess the ability to expose the characteristic information of non-stationary signals [12]. Moreover, the FT cannot define the characteristics of the temporary signal sufficiently in lower frequencies, because it calculates the averaged frequency composition over the duration of the signal [13]. Hence the use of Wavelet Transform (WT) has become more popular with non-stationery signals analysis.…”
