3D FEM Simulation of Flank Wear in Turning

AIP Conference Proceedings, 2011
This work deals with tool wear simulation. Studying the influence of tool wear on tool life, tool substitution policy and influence on final part quality, surface integrity, cutting forces and power consumption it is important to reduce the global process costs.

Advanced Wear Measurement Technique for Compression Ring Bottom Flank Wear

ASME 2009 Internal Combustion Engine Division Spring Technical Conference, 2009
Diesel 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.

Evaluation of flank wear on cutting tools

Wear, 1980
Abstract 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.

Flank wear measurement by successive image analysis

Computers in Industry, 2005
In this paper, a system based on successive image analysis is proposed for periodic measurement of flank wear in milling. The successive images are captured while the spindle is rotating. The blur of the moving images is minimized by the use of a high-speed camera and low spindle speed during the image capture. A method based on image series to measure

Fractal Estimation of Flank Wear in Turning

Journal of Dynamic Systems, Measurement, and Control, 1999
A 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 ...

Flank wear of multi-layer coated tool

Wear, 2011
Abstract Flank wear analysis on the multi-layer (TiCN/Al 2 O 3 /TiCN) coated carbide inserts has been performed after turning AISI 1045 steel. Using advanced microscope and image processing techniques including wavelet transform, we have obtained the flank wear profiles and analyzed the surface roughness and groove sizes on the coating layers to ...

Continuous Measuring of Flank Wear

1976
On-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.

Analysis of Tool Wear: Part II: Applications of Flank Wear Models

Journal of Engineering for Industry, 1970
For machining with cemented carbides and ceramics, a quantitative assessment of tool failure at the flank for establishing “limit criterion” is necessary. The arbitrarily chosen flank wear limit for all cutting speeds is not valid at higher cutting speeds because of the earlier appearance of the “inflection point” which is often taken as criterion of ...

Flank Wear of Multi-Layer Coated Tool and Wear Prediction Using Abrasion Wear Model

ASME 2009 International Manufacturing Science and Engineering Conference, Volume 1, 2009
In this paper, we have combined experimental and numerical approaches to understand the flank wear and its evolution of the multi-layer (TiCN/Al2O3/TiCN) coated carbide insert after continuous turning of AISI 1045 steels. In addition using advanced microscope techniques such as scanning electron microscope, confocal laser scanning microscope, etc., we ...

Predicting tool flank wear using spindle speed change

International Journal of Machine Tools and Manufacture, 1995
Abstract A unique technique is developed for on-line prediction of the tool flank wear in turning using the spindle speed change. A mathematical model is presented for the approach. The speed sensing element is an optical encoder mounted on the spindle shaft and interfaced to an IBM compatible microcomputer employing custom designed electronics.
