摘要:

传统上,先进制造工艺的研发周期需要大量的时间和资源投入。实验可能是昂贵的,因此在相对小的规模上进行。这给通常需要大量数据的机器学习工具带来了问题,否则这些工具可能会加快开发周期。我们通过将条件生成对抗网络(GANs)应用于新兴制造工艺,剪切辅助加工和挤出(ShAPE)的扫描电子显微镜(SEM)图像,建立了以前的工作。我们生成逼真的图像条件回火和实验参数或材料属性。通过这样做,我们能够将机器学习集成到开发周期中,允许用户立即可视化特定工艺参数或特性产生的微观结构。这项工作形成了一个从根本上理解制造过程中的第一原理模型的情况下,一个新的方法的技术骨干。通过从拓扑角度表征微观结构,我们能够评估我们的模型捕获实验扫描电子显微镜(SEM)样品的广度和多样性的能力。我们的方法是成功地捕捉所考虑的过程中产生的视觉和一般的微观结构特征,与分析突出方向,以进一步提高我们的合成图像的拓扑现实主义。

英文摘要:

The research and development cycle of advanced manufacturing processes traditionally requires a large investment of time and resources. Experiments can be expensive and are hence conducted on relatively small scales. This poses problems for typically data-hungry machine learning tools which could otherwise expedite the development cycle. We build upon prior work by applying conditional generative adversarial networks (GANs) to scanning electron microscope (SEM) imagery from an emerging manufacturing process, shear assisted processing and extrusion (ShAPE). We generate realistic images conditioned on temper and either experimental parameters or material properties. In doing so, we are able to integrate machine learning into the development cycle, by allowing a user to immediately visualize the microstructure that would arise from particular process parameters or properties. This work forms a technical backbone for a fundamentally new approach for understanding manufacturing processes in the absence of first-principle models. By characterizing microstructure from a topological perspective we are able to evaluate our models' ability to capture the breadth and diversity of experimental scanning electron microscope (SEM) samples. Our method is successful in capturing the visual and general microstructural features arising from the considered process, with analysis highlighting directions to further improve the topological realism of our synthetic imagery.
