本文概述了当前的模拟方法，描述了磨削过程和磨床结构的相互作用，例如振动、偏转或热变形。详细显示了描述接触区域内砂轮与工件相互作用的影响的创新工艺模型。此外，还讨论了代表磨床及其部件的静态和动态行为的仿真模型。对过程结果影响较大的机床部件比影响较小的机床部件建模得更详细。本文的关键问题是过程和机床模型的耦合，用于预测过程和机器的交互。介绍了几种耦合方法并记录了仿真结果的改进。基于所提出的仿真方法，可以更有效地设计磨削工艺和机器，从而提高工件质量和工艺稳定性。
This article presents an overview of current simulation methods describing the interaction of grinding process and grinding machine structure, e.g., vibrations, deflections, or thermal deformations. Innovative process models which describe the effects of the grinding wheel-workpiece interaction inside the contact zone are shown in detail. Furthermore, simulation models representing the static and dynamic behaviour of a grinding machine and its components are discussed. Machine tool components with a high influence on the process results are modelled more detailed than those with low influence. The key issue of the paper is the coupling of process and machine tool models for predicting the interactions of process and machine. Several coupling methods are introduced and the improvements of the simulation results are documented. On the basis of the presented simulation approaches, grinding processes and machines can be designed more effectively resulting in higher workpiece quality and process stability.
