Evaluation of flank wear on cutting tools
Wear, 1980Abstract Replacement of a cutting tool is necessary when the tool has lost its useful life. Several experimental methods which require considerable labour and material are known for determining the tool failure. A theoretical model is presented by which the tool life can be predicted without performing exhaustive machining tests.

Fractal Estimation of Flank Wear in Turning
Journal of Dynamic Systems, Measurement, and Control, 1999A novel fractal estimation methodology, that uses—for the first time in metal cutting literature—fractal properties of machining dynamics for online estimation of cutting tool flank wear, is presented. The fractal dimensions of the attractor of machining dynamics are extracted from a collection of sensor signals using a suite of signal processing ...

Continuous Measuring of Flank Wear
1976On-line detection of a wear form which is decisive for tool life influences a machining process in favour of greater efficiency and higher safety in operation. An example of a turning operation is used here to describe a continuously working wear-measuring system for detection of flank wear.

Flank wear regulation using artificial neural networks
Journal of Mechanical Science and Technology, 2010Tool wear regulation highly influences product quality and the safety and productivity of machining processes. Hence, it is one of the most important elements in the supervisory control of machine tools. The development of this type of machine tool adaptive control is practically at its infancy because there are still no industrial solutions concerning

On-Line Sensing of Flank and Crater Wear of Cutting Tools
CIRP Annals, 1987Abstract It is well known the high interest for on line sensing of tool wear with the aim of controlling machine tools productivity from the point of view of quality and quantity. Difficulties in this measurement are also known. This paper describes a sensor based upon the TV image analysis of a worn tool.

Advanced Wear Measurement Technique for Compression Ring Bottom Flank Wear
ASME 2009 Internal Combustion Engine Division Spring Technical Conference, 2009Diesel engine technology advancements in performance and requirements for meeting emission regulations have developed new challenges for piston system durability. Increased combustion pressure and exhaust gas recirculation have severely increased the demand of the top piston ring to top piston groove surface interactions.

Analysis of Tool Wear—Part I: Theoretical Models of Flank Wear
Journal of Engineering for Industry, 1969Cutting tools of sufficient strength against failure by brittle fracture or loss of “form stability” through rise of interface temperatures, still continue to fail by a process of “wear,” which is loss of cutting tool material through gradual interaction between the work and the tool material.

Effect of Flank Wear on the Topography of Machined Surfaces
Tribology Transactions, 1993The effect of flank wear on the topography of machined surfaces is investigated by studying its effect on the shape of the tool nose. For this purpose, turning experiments were performed to produce surfaces corresponding to different levels of flank wear. The distribution of flank wear at the tool nose during these experiments caused the nose radius to

APPLICATION OF NEURAL NETWORKS TO FLANK WEAR PREDICTION
Mechanical Systems and Signal Processing, 1996Abstract Tool wear sensing plays an important role in the optimisation of tool exchange and tip geometry compensation during automated machining in flexible manufacturing system. The focus of this work is to develop a reliable method to predict flank wear during a turning process.
