Monitoring of Grinding Wheel Wear
CIRP Annals, 1992A new, optical sensor has been developed in order to monitor the cutting capacity of grinding wheels. This sensor is based on the principle of triangulation. For the investigation of the grinding wheel topography even during the grinding process the sensor has been mounted at the opposite side of the working area of an external grinding machine.

Wear, 2004
This paper declares the method for the computation of the wheel-rail surface degradation in a curve where the major surface degradation phenomenon is a combination of wear and plastic deformation. Simulating the form change of the wheel-rail contacts help to identify the risk of severe or catastrophic wear resulting from increased train speeds and axle

Prediction of wheel profile wear
Wear, 1990Abstract Prediction techniques have existed for some years to calculate wheel-rail contact patch information and the response of a vehicle to any input from track roughness. More recently, experimental information has become available relating the wear rate of a wheel or rail surface to the energy dissipated within the contact zone.

Prediction of Wheel Profile Wear
Vehicle System Dynamics, 2002A wheel profile wear prediction toot is presented and verified by using a case study. A methodology is introduced that is based an a load collective concept, where representative vehicle-track simulations are chosen to take into account parameters that affect wheel wear. Key parts of the toot are load collective design, vehicle-track simulations, wheel-

Fracture wear of grinding wheels
International Journal of Machine Tool Design and Research, 1978Abstract Evidence is presented which supports the argument that the fracture type of wear process is the most important with regard to the loss of abrasive material from a wheel during a grinding operation and that fracture occurs as a consequence of the high stresses induced in the grains by the grinding forces to which they are subjected.

Wear, 1986
Abstract The interactions between the tribological stress parameters and the measurable wear quantities during rolling with slip are examined with the help of experimental results already published and the results of some new investigations by the authors of this paper. It is from these that the following model for wear behaviour is derived. 1. (

Design of Wheel Profile to Reduce Wear of Railway Wheel
Journal of the Korean Society of Precision Engineering, 2012The wear problem of wheel flange occurs at sharp curves of rail. This paper proposes a procedure for optimum design of a wheel profile wherein flange wear is reduced by improving an interaction between wheel and rail. Application of optimization method to design problem mainly depends on characteristics of design space.

Metro trains often encounter the problem of wheel flange wear when they pass through sharp curves, especially for the poor wheel–rail profile matching or lack of lubrication, evidently increasing t...

The Wear of Grinding Wheels: Part 1—Attritious Wear
Journal of Engineering for Industry, 1971An investigation of attritious and fracture wear of grinding wheels in precision grinding is described in a two paper sequence. Attritious wear, the subject of this first paper, refers to the dulling of the abrasive grain due to rubbing against the workpiece surface.

The Wear of Grinding Wheels: Part 2—Fracture Wear
Journal of Engineering for Industry, 1971The nature and extent of grinding wheel wear in precision grinding were investigated directly from the wear particles removed from the wheel. A statistical analysis of the wear particle size distributions was developed to determine the relative amounts of bond fracture, grain fracture, and attritious wear.
