摘要
人口的快速增长提高了对工业化的需求,这为快速成型制造技术,尤其是 3D 打印技术开辟了新天地。三维打印已成为一种快速成型制造技术,应用于玩具、糖果、生物医学、电子、航空航天和汽车等各个领域。但是,对于 3D 打印材料,尤其是聚乳酸(PLA)来说,实现理想的表面光洁度是一项艰巨的任务。由于传统磨料流加工的材料去除率较低,目前的研究范围是利用离心力辅助磨料流加工工艺,通过熔融沉积法加工聚乳酸材料制成的 3D 打印空心圆柱形工件。研究采用响应面方法确定表面光洁度和表面微硬度的最佳改善百分比。使用光学轮廓仪和显微硬度测试仪检测了工件的表面特征。此外,还使用 Ansys® 软件进行了磨损建模,并通过使用 Reye-Archard-Khrushchev 磨损定律进行测试确认了结果。模拟结果与实验结果吻合,碎片总量为 1.4 毫克。调查结果表明,表面质量平均提高了 39.27%。实验结果表明,CFG 棒旋转对提高 Ra 和显微硬度的影响最大。此外,还发现表面光洁度和显微硬度的理想改善百分比分别为 35.34% 和 41.29 HV。
Finishing and Wear analysis of 3D-Printed Workpiece Through Centrifugal Force-Assisted Abrasive Flow Machining
The rapid population growth has raised the need of industrialization which has opened a new horizon for the additive manufacturing, especially in the area of 3D printing technology. 3D printing has immersed as the additive manufacturing technique which finds its application in every domain including toys, confectionaries, biomedical, electronics, aerospace and automobile. But achieving the desirable surface finish is a difficult task for 3D-printed material especially poly lactic acid (PLA). Due to less material removal in traditional abrasive flow machining, the scope of the current investigation is to finish 3D-printed hollow cylindrical workpiece made of PLA material by Fused deposition method using Centrifugal force-assisted abrasive flow Machining process. The investigation was carried out to determine the optimum percentage improvement in surface finish and surface micro-hardness using Response surface methodology. Using an optical profilometer and a micro-hardness tester, the surface characteristics of the workpiece were examined. Additionally, wear modeling was carried out using the Ansys® software, and the outcomes were confirmed through tests using Reye–Archard–Khrushchev wear law. The simulation results were in good confirmation of experimental results with total debris of 1.4 mg. The findings of the investigation indicate an average improvement in surface quality of 39.27%. The experimental results show that the major influence on enhanced Ra and micro-hardness comes from CFG rod rotation. Also, the ideal percentage improvements in surface finish and micro-hardness are found to be 35.34% and 41.29 HV, respectively.
