模拟方法的预测精度受到其理论背景的限制。这一事实可能会导致在调查高复杂性系统时，例如包含表现出相当不同行为的组件时，仿真质量方面的缺点。为了克服这一局限性，越来越多地使用联合仿真方法，结合不同仿真学科的优势。这就是为什么我们提出了一种新的策略，用于切削过程的动态仿真。该方法耦合拉格朗日粒子方法，如平滑粒子流体动力学（SPH）方法，和多体系统（MBS）工具，使用联合仿真。我们证明了新方法的能力，通过提供正交切削过程的模拟结果，并将其与实验数据进行比较。
The prediction accuracy of a simulation method is limited by its theoretical background. This fact can lead to disadvantages regarding the simulation quality when investigating systems of high complexity, e.g. containing components showing a fairly different behavior. To overcome this limitation, co-simulation approaches are used more and more, combining the advantages of different simulation disciplines. That is why we propose a new strategy for the dynamic simulation of cutting processes. The method couples Lagrangian particle methods, such as the smoothed particle hydrodynamics (SPH) method, and multibody system (MBS) tools using co-simulations. We demonstrate the capability of the new approach by providing simulation results of an orthogonal cutting process and comparing them with experimental data.
