The use of 3D surface analysis techniques to investigate the wear of matt surface finish femoral stems in total hip replacement
… combined give an insight into the mechanism of wear behind the loosening and failure of matt surface finish femoral stems. By examining stems which have been explanted from patients, a method of wear classification has been developed, and also 3D surface measurement techniques have been employed …

Multivariate tool condition monitoring in a metal cutting operation using neural networks
… assess the ability of a neural network in tool wear diagnosis. The application of a linear neural network model in the form of a Single Layer Perceptron (SLP) could not satisfactorily classify the cutting data into the two tool state classes desired. The non-linear nature of the cutting data led …

Design and characterization of a smart bit for in-situ force measurement, using capacitive load cells and acoustic spectra analysis to determine rock type and tool wear in rock excavation process
… work investigates methods for determining tool wear and material type with a sensing system, which would enable operators to make decisions using objective feedback from a safer location. Continuous mining machine operators must determine tool wear and material type during operation, and they …

Tool wear monitoring in turning using fused data sets of calibrated acoustic emission and vibration
… of this research is to develop an on-line tool wear condition monitoring intelligent system for single-point turning operations. This is to provide accurate and reliable information on the different states of tool wear. Calibrated acoustic emission and vibration techniques were implemented to …
