在本研究中，提出了一种新的框架，模型之间的瞬态相互作用的任意立铣刀的几何形状和工件的切削齿。在这个框架中，工件的几何形状建模使用体素化的表示，动态更新的材料被局部删除的每个齿的切削刀具。采用光线投射法模拟刀具切削面与工件材料相交的过程。这种射线投射方法被用来计算瞬时未变形切屑厚度。由此产生的基于体素的模型框架进行了验证，通过比较预测与实验测得的铣削力。体素尺寸对模型预测的影响进行了评估，并研究了模型描述顺序加工道次的交互作用的能力。这个基于体素的模型框架的影响，预测局部表面光洁度和计算的可扩展性复杂的切割配置的实用程序进行了简要讨论。
In the present study, a novel framework is presented that models the transient interaction between cutting teeth of an arbitrary end mill geometry and a workpiece. In this framework, the workpiece geometry is modeled using a voxelized representation that is dynamically updated as material is locally removed by each tooth of the cutting tool. A ray casting approach was used to mimic the process of the cutting faces of the tool intersecting the workpiece material. This ray casting approach was used to calculate the instantaneous undeformed chip thickness. The resulting voxel-based model framework was validated by comparison of predictions with experimentally measured milling forces. The effect of voxel size on model predictions was evaluated, and the ability of the model to describe the interactive effects of sequential machining passes was also investigated. Implications of this voxel-based model framework in terms of utility for predicting local surface finish and computational scalability of complex cutting configurations are briefly discussed.
