The introduction of a bi-adaptive smoothed particle hydrodynamics formulation beneficial for machining process simulations

Machining is one of the most important industrial production processes and, therefore, it is of great interest to have a tool suitable to describe the behavior of a real machined workpiece in a simulation. Due to its meshless nature, the Smoothed Particle Hydrodynamics (SPH) method is a quite promising, but frequently not well known alternative to mesh-based techniques, with the Finite Element Method leading the way, when simulating cutting processes. In order to demonstrate this, we present a broad variety of simulation results generated by our enhanced, bi-adaptive SPH cutting algorithm and evaluate them with respect to experimental data. But not only the final results, also the way how to extend the basic SPH code for solids to two adaptive components in order to meet the special requirements demanded by the cutting scenario, the ASPH extension and a newly developed refinement algorithm, is presented.
