Abstract
The purpose of this study is to introduce a new approach of high
speed cutting numerical modelling. A lagrangian Smoothed Particle
Hydrodynamics (SPH) based model is carried out using the
Ls-Dyna software. SPH is a meshless method, thus large
material distortions that occur in the cutting problem are easily
managed and SPH contact control permits a “natural” workpiece/chip
separation. Estimated chip morphology and cutting forces are
compared to machining dedicated code results and experimental data.
The developed SPH model proved its ability to account for continuous
and shear localized chip formation and also correctly estimates the
cutting forces, as illustrated in some orthogonal cutting examples.
