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来评估加工操作期间变形，并将有助于过渡到行业4.0。在过去的几年中，努力集中在方法的发展上，这些方法可用于非破坏性评估加工变形。在AMRC上开发的一种表现出巨大希望的方法是使用X射线衍射，该X射线衍射已被证明可以确定加工变形。该项目旨在建立AMRC现有的工作体系，以进一步开发此方法，以允许对基于NI的Superalloy组件的变形进行定量评估，其最终目的是开发一个可以集成到加工钻机上的过程，从而提供了变形积累的实时数据。因此，该项目将导致大幅节省的成本能够实现，因为工具生活将实时确定，同时还提供了准确的变形量度，进一步促进了制造过程的数据驱动转换。为了实现概述的目标，该项目将集中于开发基于NI的超合金的方法，这些合金在加工和衍射中提供了独特的挑战组合，这将使能够确定并扩展到基于实验室的系统。项目目标是： - 通过高分辨率实验，使用同步辐射在具有不同变形级别的机加工样本上进行高分辨率实验。 - 扩展从同步加速器衍射到基于实验室的前静脉方法的经验教训，包括确定基于实验室的系统中理论的可用限制以及建立数据分析协议协议和算法。 - 原位整合到加工钻机的试验。
