Modeling of Orthogonal Metal Cutting Using Adaptive Smoothed Particle Hydrodynamics

Chapter
Part of the Lecture Notes in Production Engineering book series (LNPE)

Abstract

This contribution provides an overview over different aspects of the numerical modeling of orthogonal metal cutting using adaptive Smoothed Particle Hydrodynamics. First, the basic principle of the employed spatial discretization technique and its application to the equations of solid continuum mechanics are introduced. Furthermore, a brief description is given of the most important extensions to this meshless Lagrangian simulation method that are necessary to correctly model the process of metal cutting, e.g. a variable resolution scheme. Here, references to in-depth literature are provided where necessary. Second, the applicability of the introduced enhanced discretization technique to model cutting processes is shown. To that end, the results of orthogonal cutting simulations for a steel of type AISI 1045 are analyzed in terms of chip formation, stress distribution as well as the cutting force, and they are compared to experimentally obtained data.
