Interrelationships between Acoustic Emission and Cutting Force in Rock Cutting

Table 1

Summary of earlier acoustic emission monitoring studies of rock-cutting.

Authors	Materials	Work and results	AE processing methods
Ma 1996 [17]	Limestone, granite, diorite, marl, etc.	Different rocks have different acoustic emission frequencies.	Not described
Kovacevic 1998 [20]	Magnesia chromite, sintered magnesia, bauxite	RMS of AE was investigated to establish the function of drilling depth for the study of material (metal) removal mechanisms.	Fast Fourier transform (FFT); PSD by using autoregressive moving average(ARMA) model
Momber 2000 [21]	Concrete materials	Integrated AE technique and visualization method to monitor erosion process of concrete material.	FFT and frequency domain analysis
Kovacevic 2002 [22]	Gray cast iron	Proposed an energy dissipation model and interpreted the relations of AE signal with energy dissipation.	PSD by using ARMA model; FFT and frequency domain analysis
Karakus 2014 [23]	Hard rock	Make it possible to estimate the depth of cut, weight on the bit (WOB), and torque on the bit (TOB) by simply using the time spectrum of the AE signals.	FFT and frequency domain analysis
Xiao 2018 [24]	Concrete	Spectral analysis of the AEs indicated that the higher ROP and larger cutting size were correlated with a higher AE energy and a lower AE frequency.	FFT and frequency domain analysis
