Novel application of LFW to enable near net shape forming of components

由GKN航空航天公司牵头的一个应用研究项目，采用了现有的连接技术-线性摩擦焊接(LFW)，并以一种新颖的方式应用于近净成形，导致英国制造业整体竞争力的阶段性变化。它显著降低了原材料需求、加工时间和成本，大大提高了“买到飞”的比率和环境可持续性。环境效益将通过整个供应链实现，减少了材料供应和软金属零件制造过程中的能源消耗。这项工作将与汤普森摩擦焊接公司合作，他们在使用LFW方面拥有成熟的经验，伯明翰大学将为焊接特性、优化和验证提供学术支持。这种先进的制造技术将使高价值、低成本、环保的制造能够在竞争日益激烈的全球市场中在英国得到开发。该项目解决了本次电话会议中确定的两个挑战：金属/净形状混合结构的智能加工和新制造工艺能力的创新。

An applied research project led by GKN Aerospace, taking an existing joining technique, Linear Friction Welding (LFW), and applying it in a novel way to achieve near net shape forming, resulting in a step-change in overall UK manufacturing competitiveness. It enables both a significantly reduced raw material requirement and machining time and cost, delivering a much improved 'Buy to Fly' ratio and environmental sustainabilty. Environmental benefits will be achieved through the whole supply chain from reduced energy used during material supply and part manufacture of both hard and soft metals.Work will be undertaken with Thompson Friction Weld, who have a proven experience in using LFW, and academic support from the University of Birmingham for weld characterisation, optimisation and validation. This advanced manufacturing technology will enable high value cost efficient environmentally beneficial manufacturing to be exploited in the UK in an increasingly competitive global market. The project adresses two challenges identified in this call: Intelligent processing of metals/net shape hybrid structures and Innovation in new manufacturing process competencies.
