Abstract
An analysis of published experimental and theoretical slip-line field results for the metal cutting process suggests that, when the tool and workpiece are of high elastic modulus, a reasonable first approximation to the rake-face loading will consist of uniformly distributed normal and tangential stresses over the contact length. An indication of the form of the stress distribution at the tip of a cutting tool is therefore obtained from an isothermal–elastic solution for a two-dimensional infinite wedge, loaded antisymmetrically by uniform normal and tangential stresses adjacent to the apex. Only a preliminary assessment of the results is made, in relation to cutting tool wear and fracture problems, since a more detailed assessment will await a complete thermoelastic solution to the problem.
