The project aims to develop a non-destructive tool for the evaluation of deformation during machining operations and will aid the transition to Industry 4.0. Over the past few years efforts have concentrated on the development of methodologies that can be used to non-destructively evaluate machining deformation. A method developed at the AMRC that has exhibited considerable promise is the use of X-ray diffraction that has been shown to qualitatively determine machining deformation. This project aims to build upon the existing body of work at the AMRC to develop this methodology further to allow the quantitative evaluation of deformation on Ni-based superalloy components with the ultimate aim of developing a process that can be integrated onto machining rigs providing real-time data of deformation accumulation. The project will hence result in significant cost savings to be realised as tool-life will be determined in real-time, whilst also providing an accurate measure of deformation further aiding in the data-driven transformation of manufacturing processes. In order to achieve the aims outlined, the project will concentrate on developing the methodology on Ni-based superalloys that offer a unique combination of challenges both in machining and diffraction that will enable a robust methodology to be determined and extended to lab-based systems. The project objectives are: -Methodology development and advanced understanding through high resolution experiments using synchrotron radiation on machined samples with different levels of deformation. -Extension of lessons learned from synchrotron diffraction to lab-based ex-situ methodologies including the determination of the usable limits of theory in lab-based systems and the establishment of data analysis protocols and algorithms. -Trials of in situ integration to machining rigs.

该项目旨在开发一种非破坏性工具，用于评估机加工过程中的变形，并将有助于向工业4.0过渡。在过去的几年里，人们的努力集中在开发可用于非破坏性评估加工变形的方法上。AMRC开发的一种具有相当大前景的方法是使用X射线衍射，该方法已被证明可以定性地确定加工变形。该项目旨在建立在AMRC现有工作的基础上，进一步开发这种方法，以便对镍基高温合金部件的变形进行定量评估，最终目标是开发一种可以集成到加工平台上的工艺，提供变形积累的实时数据。因此，该项目将实现显著的成本节约，因为工具寿命将实时确定，同时还提供了变形的准确测量，进一步帮助制造过程的数据驱动转型。为了实现上述目标，该项目将专注于开发镍基高温合金的方法，这些方法在加工和衍射方面提供了独特的挑战组合，这将使一种强大的方法得以确定并扩展到实验室系统。该项目的目标是：- 通过在不同变形程度的加工样品上使用同步辐射进行高分辨率实验，开发方法并加深理解。- 将从同步加速器衍射中吸取的经验教训推广到实验室非现场方法，包括确定实验室系统中理论的可用限度，以及建立数据分析协议和算法。- 现场集成到加工设备的试验。
