在航空航天工业中，磨削工艺产生的表面形貌是所生产零件的主要质量特征。使用点云对单个晶粒进行建模的模拟系统是预测这些形貌和工艺力的灵活解决方案，考虑了几种影响，例如，谷物的磨损。所得到的表面形貌还受到工艺偏差的影响。在本文中，一个基于点的几何物理为基础的磨削仿真的扩展，它允许建模的过程偏转的影响。进行了实验，通过将产生的工件表面与模拟结果进行比较来验证该模型。
In the aerospace industry, surface topographies resulting from grinding processes are a major quality feature of the produced parts. Simulation systems using point clouds for modeling individual grains are a flexible solution to predict these topographies and the process forces, taking several effects into account, e.g., the wear of the grains. The resulting surface topographies are additionally influenced by process deflections. In this paper, an extension of a point-based geometric physically-based grinding simulation is presented, which allows modeling the influence of process deflections. Experiments were conducted in order to validate the model by comparing the resulting workpiece surfaces to the simulation results.
