摘要
聚醚醚酮(PEEK)具有优异的机械性能和生物相容性,已被广泛应用于各个领域。本研究通过三维打印和铣削混合工艺研究了如何高效、高质量地定制制造 PEEK 组件。首先,通过比较两种典型的混合工艺类别并进行实验,选择并验证了交替混合工艺。其次,设计了一套程序来实现混合工艺的工程应用自动化,以避免手工编程的弊端。然后,考虑到刀具长度和混合工艺过程中可能出现的干扰,提出了一种模型分割算法,即避免干扰的交换原则(EPAI)。基于引入的 EPAI 和 Python 编程语言,提出了增减混合制造(ASHM)数据处理程序,并通过对传统 3D 打印代码的后处理实现了该程序。最后,进行了可行性实验。实验结果验证了混合制造工艺可用于制造具有复杂内部特征的零件。零件的表面粗糙度 Ra 和尺寸误差 L 分别降低了 75.5% 和 85.2%,而剪切强度 τ 则提高了 14.1%。与传统铣削工艺相比,材料消耗减少了 48.7%。
Study on hybrid 3D printing and milling process for customized polyether-ether-ketone components.
Polyether-ether-ketone (PEEK) has been widely applied in various fields due to its excellent mechanical properties and biocompatibility. The efficient and high-quality customized manufacturing of PEEK components are investigated in this study by the hybrid 3D printing and milling process. At first, the alternating hybrid process is selected and verified by comparing two typical hybrid process categories and conducting experiments, respectively. Second, a set of procedures are designed to automate the engineering application of the hybrid process trying to avoid the disadvantages of manual programing. Then, considering the tool length and possible interferences during the hybrid process, a model segmentation algorithm, namely, the exchange principle of avoiding interference (EPAI) is proposed. Based on the introduced EPAI and the programing language Python, the additive and subtractive hybrid manufacturing (ASHM) data processing procedure is proposed and realized by post-processing of the conventional 3D printing codes. Finally, the feasibility experiments have been conducted. The experimental results verify the hybrid manufacturing process in the fabrication of parts with complex internal features. The surface roughness Ra and dimensional error L of the parts have been reduced by 75.5% and 85.2%, respectively, while the shear strength τ has been increased by 14.1%. Compared with conventional milling process, the material consumption is reduced by 48.7%.
