Transient phenomena in the grinding process

Abstract

Local contact displacements resulting from the elastic deformation of the tool and the blank, were studied using the finite-element and by experiments. Graphical and analytical expressions for the cutting force, with harmonical and stochactic components, were obtained. Previously published research on the behaviour of the contact between the grinding wheel and the workpiece has been based, on the assumption that the contact deformations represent a direct function of both the normal and the tangent forces acting on the wheel or its grains during the grinding process, without taking into account the attrition and breaking of the grains [...].
