Grinding wheel effect in the grind-hardening process

The International Journal of Advanced Manufacturing Technology, 2007
The grind-hardening process is based on the utilization of the generated heat in the grinding zone for inducing a metallurgical transformation on the surface of the ground workpiece. The workpiece surface is locally heated above the austenitization temperature and subsequently is quenched to increase surface hardness. A theoretical model was developed

Grinding Process Instability

Journal of Engineering for Industry, 1969
The paper describes a theoretical investigation on chatter vibrations of cylindrical plunge grinding. The system grinding machine-grinding wheel-workpiece is represented as a closed loop system with two feedback paths, one due to the machine tool structure, the other to the regenerative effect of the grinding wheel.

Contact Processes in Grinding

Applied Mechanics and Materials, 2015
The relevance of investigating the problem of loading a diamond abrasive tool with a metallic binder to improve the efficiency of finishing treatment of a wide range of high-strength materials is addressed in the paper. The results of theoretical and experimental studies of the formation of a greasy layer on the surface of diamond wheels in the ...

Kinematics of the grinding process

Materials Today: Proceedings, 2021
Abstract The possibility of chip removal is governed by the section thickness, properties of metal under deformation speed, geometric parameters of cutting edges of the wheel. Randomized geometry and arbitrary location of cutting edges on the work surface of grinding wheel allow the application of probabilistic-statistical approach for description of

Visualization of Grinding Processes

1999
In grinding technology, the application of superabrasives and increasing demands for higher productivity and higher quality require an appropriate selection of optimum set-up parameters. An efficient way to determine and test these parameters is modeling and simulating the grinding process.

Modeling and Predicting Grinding Force of the Grinding Process

Advanced Materials Research, 2014
A new method for predicting the grinding force is developed in this paper. The grinding forces model is build by divided it into cutting deformation force and sliding force and combine the undeformed chip thickness which assume the height of grits obey the Rayleigh distribution.

Development of the process model for plunge grinding and optimization of grinding process

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2011
This article presents improved grinding roughness model established for cylindrical plunge grinding though analysing the existing roughness models. The proposed roughness model is to consider the uncertain effects of grinding, such as changes of grinding conditions and circumstance, as grinding procedure is progressed.

Model of Gear-Grinding Process

CIRP Annals, 1995
Abstract The mathematical model of a generating gear grinding process is presented in the paper. Detailed analysis of the creation of the tooth profile resulted in evaluation of the shape of a material layer being removed in a particular generating stroke of a grinding wheel and consequently in calculation of grinding forces, power density ...

Grinding Equipment and Processes

1989
AbstractMetal is removed from the workpiece by the mechanical action of irregularly shaped abrasive grains in all grinding operations. This article discusses three primary components of grinding wheels, namely, abrasive (the cutting tool), bond (the tool holder), and porosity or air for chip clearance and/or the introduction of coolant.
