A unique UK national capability for large optics manufacture and associated technologies has been exploited. This case study describes the benefits realised from research into high precision surface-removal processes plus metrology, applied to large area functional surfaces producing precisions down to nanometres. Research into metrology for optical manufacturing, into increasing the dynamic range of a CNC polishing machine and into the issues associated with scaling up from prototype to commercial mass production of large off-axis aspheric mirror-segments for future extremely large telescopes has made a significant contribution to the progress of the ESO European Extremely Large Telescope project and has brought commercial benefits to Zeeko Ltd.
The UltraMill machine was developed at Brunel University in 2008, in collaboration with Ultra Precision Motion (UPM) Ltd, to help support UK and European manufacturing SMEs in high value manufacturing sectors, particularly in ultra-precision and micro manufacturing. The machine has a novel design and the sub-systems and machine elements have a number of technological innovations. Two international patents have been granted to protect the IP within the machine. A surface roughness of 4-6 nm was micro-milled on non-ferrous metal components by the UltraMill in 2008, which at the time was the finest engineering surface achieved by ultra-precision micro-milling in the world.
A licence agreement was signed with ITP Group (UK) in 2012 for the commercial production of the UltraMill. This was ITP's first entry into the high-precision milling market. ITP realigned their production systems to begin manufacturing the UltraMill in late 2012 and have manufactured 3 machines to date.
Contour Fine Tooling, which leads the worldwide market in the field of diamond cutting tools, was inspired by the UltraMill, and developed the first diamond micro-milling tool in the world. The UltraMill was used to test the tool's capabilities and feasibility; the new tool has since been successfully sold. It is now being used to manufacture a number of high-value products. In particular it is used by Apple to produce the bevelled edges of the iPhone 5S. Apple currently manufactures 150,000 iPhone 5S units per day.
University of Huddersfield research into surface metrology, carried out as part of the EU-funded SURFSTAND project, has led to worldwide changes in manufacturing. Nine ISO standards related to measuring the surface roughness of parts have been developed as a result, influencing practices in sectors ranging from aerospace and automotive engineering to microelectronics and bio-implant production. Consequently, all quantitative 3D surface measurement carried out in the world now draws on the research. Instrument manufacturers and the National Physical Laboratory have also implemented the standards, while software developed as part of the research has been incorporated by a leading industrial partner, significantly enhancing the company's offering and market position.
This case study describes the impact of interdisciplinary research at MMU that has focused on the development and characterisation of hygienic and antimicrobial surfaces across a range of applications, particularly with regard to food hygiene, which in turn impacts on food quality, reduced waste and consumer health across the international food industry. This 20-year collaboration has enabled identification and specification of properties of putative hygienic/antimicrobial surfaces, whilst testing them in vitro and in situ. This research has had international impacts in areas including health (cross-contamination) hygienic design (food processing), and development of standards for testing novel materials.
A manufacturing process developed by Bradford researchers has revolutionised the way endodontists perform root canal treatments. When coated with a hydrophilic polymer, the highly-filled hygroscopic material has enabled UK company DRFP to develop SmartPoint — a new endodontic technique that dramatically reduces failure rates of root canal treatments from 11-30% over five years to approximately 1%, and gives lower levels of post-operative pain when compared with conventional techniques. The technology has won three awards for innovation and DRFP has expanded significantly, with a dedicated production facility and sales team offering visits to dentists to demonstrate the benefits of the technology.
A team of Portsmouth researchers has developed a transparent polymer coating that prevents colonising bacteria from adhering to the surfaces of teeth. In addition to protecting from decay, the polymer coating has the added benefits of reducing dental erosion, alleviating root hypersensitivity, and inhibiting the staining of teeth. GlaxoSmithKline (GSK) has adopted this technology and the polymer has been successfully developed into a component of "next-generation" oral healthcare products.
A facility for precision diamond machining of optical components arose from research at Durham University to produce instruments for large telescopes, including NASA's James Webb Space telescope. This now provides a specialist service to industry, with contracts worth over £2.0M from >20 companies over the past 5 years. The users span applications including ophthalmics, automotive optics, microstructures for backlit displays and IR optics. An emerging application is the use of high precision machine metal moulds to reproduce ophthalmic lenses for spectacles. Examples include PixelOptics (USA) who make high-end electronically corrective eyewear, which has won several ophthalmic industry R&D awards, and Eyejusters (UK), which employs complex surface slide lens technology to provide low cost spectacles aimed at improving the lives of people in the developing world.
Aeroengine casings are some of the highest value components within the modern gas turbine, since their complex geometries and exotic materials lead to significant manufacturing challenges. The Advanced Manufacturing Research Centre (AMRC) has helped Rolls-Royce to overcome these challenges by developing a novel optimised manufacturing approach for aeroengine casings. This has led to substantial economic impact on Rolls-Royce as the manufacturing time for these components has reduced by up to [text removed for publication] saving more than [text removed for publication] since 2008.

Ehiasarian and Hovsepian of the Materials and Engineering Research Institute (MERI) have achieved significant economic impact through industrial uptake of their innovations in High Power Impulse Magnetron Sputtering (HIPIMS). Exploiting these innovations, HIPIMS treatments have been used by manufacturers to enhance the surface properties of millions of pounds worth of products. Applications include industrial blades, components within jet turbines, replacement hip joints, metallised semiconductor wafers and satellite cryo-coolers. Patents based on Ehiasarian and Hovsepian's research have achieved commercial success. In the REF impact period, HIPIMS machines equipped to deliver MERI''s HIPIMS surface pre-treatment have achieved sales of over £5m, and income generated through SHU's HIPIMS-related licences has totalled £403,270. In 2010 Ehiasarian's group established the Joint Sheffield Hallam University-Fraunhofer IST HIPIMS Research Centre, the first such Centre in the UK. This has broadened the industrial uptake of MERI's HIPIMS technologies and stimulated a network of sub-system providers.
Initial research into polymer nanocomposites and their formation took place at Strathclyde from 2000 - 2010. This was followed by a collaboration with the world's largest manufacturer of composite kitchen sinks, Carron Phoenix Limited, through a 6-year Knowledge Transfer Partnership (KTP) which resulted in a successful new production process of its high-end synthetic granite kitchen sinks. This led to £4 million of capital investment in new production facilities at their Falkirk site, enabling the company to sustain its leading position in the designer kitchen sink market and retain its workforce of over 400 employees in central Scotland, including the 170 workers in the composite sink division in Falkirk. Within the REF period, the research has led to the manufacture and sale of in excess of one million kitchen sinks, generating sales revenue in excess of over £50M and supporting the UK economy.
