摘要

增材制造材料的各向异性特性由于材料特性的方向性差异导致表面光洁度、切削力和可加工性的变化。这给五轴加工的刀具轨迹选择带来了挑战，以实现最佳的加工条件。此外，传统的过程建模和仿真模型和方法经常失败，导致重大误差，因为它们没有考虑到材料的各向异性。本文研究了增材制造材料加工过程中的材料行为，提出了一种方向自适应流动应力模型，用于精确的过程建模和仿真，并引入了一种适合增材制造材料铣削的自适应刀具路径选择策略。

Directional-adaptive approach in machining of additively manufactured Inconel 718

The anisotropic properties of additively manufactured materials cause variations in surface finish, cutting forces, and machinability due to directional differences in material properties. This creates challenges in tool path selection for five-axis machining to achieve optimal process conditions. Additionally, traditional models and methods for process modelling and simulation often fail, leading to significant errors, as they do not account for material anisotropy. This work investigates the material behaviour during machining of additively manufactured materials, proposes a directional-adaptive flow stress model for accurate process modelling and simulation, and introduces an adaptive tool path selection strategy tailored for milling of additively manufactured materials.
