FE Study of the Chips Morphology when Drilling Process

Abstract

The finite element modeling allows manufacturers to reduce the cost of machining operations. During a drilling operation, the chips morphology their sizes and thicknesses have a great effect on the process, whatever the material to be machined. One approach to a 3D simulation of a drilling process with the finite element program Abaqus/Explicit is displayed. We studied the morphology of chips during the drilling process, the influence of cutting parameters on their shape, size and clear velocity. This study allows us to optimize the conditions and cutting parameters for a smooth process.
