项目摘要

A Centre for Innovative Manufacture in Laser-based Production Processes is proposed. This Centre will exploit the unique capabilities of laser light to develop new laser-based manufacturing processes, at both micro and macro levels, supported by new laser source, process monitoring and system technologies.The past 25 years has seen industrial lasers replace many 'conventional' tools in diverse areas of manufacture, enabling increased productivity, functionality and quality, where for example laser processing (cut/join/drill/mark) has revolutionised automotive, aerospace and electronics production. However the penetration of laser technology into some areas such as welding and machining has been less than might have been anticipated. But recently there has been a significant 'step change-opportunity' to take laser-based processing to a new level of industrial impact, brought about by major advances in laser technology in two key areas: (i) A new generation of ultra-high quality and reliability lasers based around solid state technology (laser diode and optical fibre) has evolved from developments in the telecoms sector. These lasers are leading to systems with very high levels of spatial and temporal controllability. This control, combined with advanced in-process measurement techniques, is revolutionising the science and understanding of laser material interactions. The result of this is that major improvements are being made in existing laser based processes and that new revolutionary processes are becoming viable, e.g. joining of dissimilar materials. (ii) A new generation of high average power laser technologies is becoming available, offering controllable trains of ultrashort (picosecond and femtosecond) pulses, with wavelengths selectable across the optical spectrum, from the infrared through to the ultra-violet. Such technology opens the door to a whole range of new laser-based production processes, where thermal effects no longer dominate, and which may replace less efficient 'conventional' processes in some current major production applications.These new developments are being rapidly exploited in other high-value manufacturing based economies such as Germany and the US. We argue that for the UK industry to take maximum advantage of these major advances in both laser material processing and machine technology there is an urgent requirement for an EPSRC Centre for Innovative Manufacturing in Laser-based Production Processes. This will be achieved by bringing together a multi-disciplinary team of leading UK researchers and key industry partners with the goal of exploiting 'tailored laser light'.Together with our industrial partners, we have identified 2 key research themes. Theme A focuses on Laser Precision Structuring, i.e. micro-machining processes, whilst Theme B is focused on joining and additive processes. Spanning these themes are the laser based manufacturing research challenges which fall into categories of Laser Based Production Process Research and Laser Based Machine Technologies, underpinned by monitoring and control together with material science. Research will extend from the basic science of material behaviour modelling and laser-material interaction processes to manufacturing feasibility studies with industry.The Centre will also assume an important national role. The Centre Outreach programme will aim to catalyse and drive the growth of a more effective and coherent UK LIM community as a strong industry/academia partnership able to represent itself effectively to influence UK/EU policy and investment strategy, to promote research excellence, and growth in industrial take-up of laser-based technology, expand UK national knowledge transfer and marketing events and improve the coordination and quality of education/training provision.

提出了一个基于激光的生产过程中的创新制造中心。该中心将利用激光光的独特功能来开发新的基于激光的制造过程，在微观和宏观水平上，由新的激光源，过程监控和系统技术支持。过去25年来，工业激光器已经看到，工业激光替换了许多“常规”工具，取代了生产力和质量的工程/质量，以较高的自动化（例如，练习），以较高的速度/练习（例如，加入/练习），加入了练习，加入了工程，加入了工程，加入了工程，加入了练习，加入了工具，加入了工程，加入了工具，加入/练习，加入/练习。航空航天和电子产品。但是，激光技术进入某些领域（例如焊接和加工）的渗透远低于预期。但是最近，有一个重大的“步骤变更运动”将基于激光的处理达到新的工业影响，这是由于两个关键领域的激光技术的重大进步带来的：（i）新一代的基于固态技术（激光二极管和光学纤维）的新一代超高质量和可靠性激光器已从Telecomm secorm secords secords secords secords secords secorts Secorts Secorts Secort。这些激光器导致具有很高水平的空间和时间可控性的系统。这种控制，结合了先进的过程中的测量技术，正在彻底改变对激光材料相互作用的科学和理解。结果是，现有的基于激光的过程正在做出重大改进，并且新的革命过程变得可行，例如连接不同的材料。（ii）新一代的高平均功率激光技术正在获得，提供可控制的超平滑列车（Picsecond和femtsecond）脉冲，可在光谱中选择波长，从红外线到超维消极。这种技术为整个基于激光的新生产过程打开了大门，在这些生产过程中，热效应不再占主导地位，并且在某些当前的一些主要生产应用中可能取代效率较低的“常规”过程。我们认为，对于英国行业，在激光材料处理和机器技术中最大程度地利用了这些主要进步，紧急要求EPSRC基于激光的生产过程中的EPSRC创新制造中心。这将通过将英国领先的研究人员和主要行业合作伙伴组成的多学科团队组合在一起，以利用“量身定制的激光光”。与我们的工业合作伙伴结合，我们已经确定了2个主要的研究主题。主题A的重点是激光精度结构，即微型缓解过程，而主题B则专注于加入和加法过程。跨越这些主题是基于激光的制造研究挑战，这些挑战属于基于激光的生产过程研究和基于激光的机器技术的类别，并通过与材料科学一起监视和控制为基础。研究将从物质行为建模和激光材料交互过程的基础科学到与行业的生产可行性研究。该中心还将扮演重要的国家角色。该中心外展计划将旨在促进和推动更有效，更连贯的UK LIM社区的发展，成为一个强大的行业/学术界，能够有效地代表自己，以影响英国/欧盟政策和投资策略，促进卓越的研究，以及基于激光的技术的工业采用，基于激光的技术的增长，扩大了英国知识转移和营销活动，并扩大了教育/培训的协调和培训。
