Title The Challenge to Manufacturing of an Ageing World Population
People are living longer. With age comes an increase in degeneration of bone and joints due to wear and tear, and the onset of arthritis. The effects of the latter disease is one of the most common causes of the need for joint replacement, especially of the knee.
The increasing consumption of energy-dense food, high-sugar content drinks, often coupled with physical inactivity have led to more than a three-fold rise in obesity over the last thirty years.
Obesity is a major contributor to osteo-arthritis (OA), smoking, high consumptions of caffeine and of red meat are known to promote rheumatoid arthritis (RA).
These diseases are two of the most common causes of the need for joint replacement. They are about three times more likely to occur in women than in men.
Joints in the body may be replaced by metal alloys, ceramics and polymers: including stainless steel, cobalt – or titanium-based alloys, oxide ceramics, ultra-high molecular weight polythene.
These materials will be discussed in Keynote address and their engineering properties that make them suitable for joint replacement. (Wear and friction, fatigue and creep and corrosion of these materials will be discussed).
Although established methods of manufacture are mainly used to produce these materials to specified requirements, the increasing place of unconventional processes will be discussed, including electrochemical machining ((ECM) and electropolishing.
The need for surface coatings to enhance bio-compatibility with adjacent tissue will be explained, and the quest for improvements in this aspect of manufacturing technology.
The increasing applications for computer-aided design and manufacture (CAD/CAM) will be addressed. The CAD/CAM link to rapid prototyping (RP), especially for creating three-dimensional solid models of proposed implants will be presented.
Finally, future trends for robotic-assisted joint replacements will be highlighted.
McGeough's books include “Principles of Electrochemical Machining” (1974), “Advanced Methods of Machining” (1988), “Micromachining of Engineering Materials” (editor, 2001) and “The Engineering of Human Joint Replacements (2013).

Title New Paradigm of Manufacturing for Electronics_Technology of Printed Electronics
Printed electronics has been the one of the most attractive technologies for manufacturing electronics like RFID, sensors, OPV, OLED and OTFT. Those electronics has been manufactured by the batch process mostly, which requires more higher cost up to now. Therefore the effort to reduce the cost has been carried out. One of the technologies for these effort is the printed electronics. For mass production of these electronics to reduce the cost, the flexible substrate must be used by printing technology which is very popular in graphical publication. As a basic concept of printed electronics, R2R technology is served as platform for all the components of electronics, which will be introduced in each field for sensors, OPV and OLED. However the electrical performance like resistance, conductivity, mobility and efficiency are proved to be very poor compared to the current manufacturing technology. In this sense, the related industry is trying to find a more applicable industrial field which printed electronics can be applied successfully. This current situation and limitation of printed electronics will be discussed and future of this technology will be discussed.

Title Augmented reality assisted maintenance and disassembly
Maintenance and disassembly both require dismantling of components, whether for replacement or remanufacturing.
Extensive laboratory tests have shown that augmented reality can reduce cognitive load, and offer a more intuitive working environment to the operators. Service technicians working on site can consult remote experts for providing necessary advice via AR interfaces. Equipment can be made to communicate with technicians, providing them with the current and historical states of operating conditions in real time. Psychomotor studies can help reduce operator fatigue and provide them with the best posture to alleviate physical strain in maintenance and disassembly operations.
This presentation also touches on the quality of maintenance operations including the estimation of cognition load and fatigue of operators, measurement of comfort and safety, reliability and risk assessment, etc. Real-time data capture and analysis using IIoT and cloud technology is another potential area to be considered.

Speaker Prof. Hendrik Van Brussel
Title Design of Holonic Manufacturing Systems
The introduction of CIM (Computer Integrated Manufacturing) systems in the 1980s, aiming at integrating automatic workstations into fully automated factories, was not successful. The root causes of this failure were that the subsystems to be integrated were not suitably designed for easy integration into a larger system, and the adopted hierarchical control schemes made the overall system not robust against disturbances (e.g. machine breakdown, rush orders) and system changes (e.g. adding a new machine). This situation stimulated the authors to embark on a research programme on ‘design for the unexpected’. It defined how subsystems have to be designed so that integration into larger systems becomes easier and how such an integrated system can be controlled so that it can cope with disturbances.
In the keynote paper, the underlying ‘laws of the artificial’ and the salient features of holonic manufacturing systems (HMS) are outlined. The PROSA reference architecture, defining the basic structure of any HMS, is briefly explained. It will be explained how coordination and control of the HMS is achieved by a holonic execution system (HES), based on a biologically inspired DMAS (Delegate Multi-Agent System).
The power and universality of the PROSA/DMAS architecture will be demonstrated by some case studies from manufacturing and robotics.

Title Research and development towards next-generation metal cutting technology
Metal cutting is still one of the most important fundamental manufacturing processes which creates shapes of most industrial products directly or indirectly utilizing dies and molds. Hence, advances in metal cutting technology lead to great benefit to society such as cost reduction, performance improvement, and lead time reduction of existing products, and even realization of new products.
It this talk, new metal cutting technology, which has recently been developed towards more precise, more efficient, and fully automated metal cutting, is introduced, including “Elliptical Vibration Cutting”, “Speed-Differing Multi-Milling”, and “Chip-Guiding Cutting”. The elliptical vibration cutting has realized ultraprecision/micro machining of difficult-to-cut materials like hardened die steel, and it is commercialized mainly for precision die/mold machining. The speed-differing multi-milling improves machining efficiency and accuracy considerably, e.g. by several times, by suppressing regenerative chatter vibration in multi-milling with a flexible structure, and as an example it is utilized for mass production of precision steel plates. The chip-guiding cutting has recently been proposed to avoid chip jamming, and it is expected that it will not only achieve the avoidance but also reduce cutting force/temperature by combining chip-pulling technology.

Title Enriching additive manufacturing metrology
Additive manufacturing facilitates the manufacture of highly complex geometries – a bonus for designers but a headache for metrologists. The keynote will address a new approach to metrology which can help to solve some of the outstanding issues in additive (and more generally, digital) manufacturing. Information-rich metrology (IRM) is a new term that refers to an approach, or better a philosophy of thought, where the conventional paradigm of measurement (measurement information gathered solely through the physical interaction of the instrument with the measured object) is transcended, thanks to the introduction and active role of multiple novel sources of information. The overarching goal of IRM is to encompass and homogenise all those measurement scenarios where information available from heterogeneous sources, for example, from the object being measured, the manufacturing process that was used to fabricate it, the workings of the measurement instrument itself, as well as from any previous measurements carried with any other instrument, is gathered and somewhat incorporated with an active role into the measurement pipeline in order to ultimately achieve a higher-quality measurement result (better metrological performance, shorter measurement times, smaller consumption of resources). Examples of IRM in action in additive manufacturing will be presented, including the measurement of form and texture, external and internal features, and post- and in-process.
Richard is currently a professor in metrology at the University of Nottingham and prior to this spent 25 years at the National Physical Laboratory. Richard's research is dominated by what he calls "information-rich metrology": the enhancement of manufacturing metrology through the use of a priori information, often utilising concepts from artificial intelligence.

Title Opportunities and Applications of 3D Additive Manufacturing
3D Additive Manufacturing (AM) is defined by ASTM as the "The process of joining materials to make objects from 3D model data, usually layer upon layer, as opposed to subtractive manufacturing methodologies”. Traditional manufacturing has fuelled the industrial revolution that has enabled our world today, yet it contains inherent limitations that point to the need for new approaches. Casting, forming, molding, and machining are complex processes that involve tooling, machinery, computers, and robots. The competitive advantages of 3D AM are geometrical freedom, shortened design to product time, reduction in process steps, mass customization and material flexibility. 3D AM simplifies the laborious process of producing complex parts while reducing cost. It is predisposed to industry sectors that require high mix, low volume parts or customised parts.

Title Abrasive-Free Planarization of Functional materials by Catalyst Referred Etching
A novel abrasive-free planarization method named catalyst-referred etching (CARE) was developed. The apparatus of CARE is nearly the same as that of conventional CMP. As a unique difference, a polishing pad coated by a catalytic material with the thickness of about 100nm is used in CARE. During the processing, topmost areas of the work surface, which contacts more frequently with the catalytic pad, are preferentially etched off through the catalytically induced chemical etching, leading to quick and effective flattening of work surface. Currently, CARE with pure water, named water-CARE, has been developed, in which Pt and pure water are employed respectively for a catalyst and an etchant. This method has lately attracted considerable attention to be a new planarization method with natures of clean room compatibility and eco-friendliness. This paper reviews the CARE method from the viewpoints of the equipment configuration and applicability to functional materials. 4H-SiC, GaN, and SiO2 glass substrates are respectively employed as single crystalline and amorphous materials. In the crystalline materials, geometrically and crystallographically well-ordered surface with a step-and-terrace structure was observed over the whole area of the 2 inch substrate. The height of the step was a single bilayer. Also in the glass material, atomically smoothed surface was obtained.
Professor Kazuto Yamauchi received his Ph.D. from Osaka University, Japan in 1991. He has occupied the professor position at Osaka University since 2003, and has been a Leader of Center of Excellence for Atomically Controlled Fabrication Process of Osaka University since 2008.

Title Advances in X-ray Computed Tomography for Dimensional Metrology
X-ray computed tomography (CT) recently emerged as an advanced measuring technology for dimensional and geometrical measurements in industry. CT coordinate measurements offer several advantages with respect to tactile and optical coordinate measurements. For example, CT enables non-destructive and non-contact inspections of features that can be both accessible (e.g. external) or difficult to be accessed (e.g. internal), with simultaneous material analysis and dimensional quality control. Typical industrial applications are: CAD comparison, wall-thickness analysis, defect analysis, analysis of assembly, wear evaluation, fibre orientation analysis and quality assessment of complex additive manufactured parts. The dimensional measurement accuracy of CT systems must be verified in order to achieve traceability to the unit of length (meter) and comparability of CT to other dimensional measuring techniques. With this aim, CT metrological performances must be periodically tested and uncertainty of CT dimensional measurements must be determined for each specific measurement task. Metrological performance verification is usually conducted by measuring CT-specific reference objects featuring calibrated dimensions. This presentation describes the reference objects developed at University of Padova for the assessment of length measurement errors, metrological structural resolution, accuracy of CT porosity analysis, accuracy of micro-gap measurements and CT geometrical errors. The CT Audit international intercomparison, coordinated by University of Padova, demonstrated that only a minority of participants were able to perform length measurements with errors below their CT systems’ specification. Moreover, the participants had difficulties in evaluating measurement uncertainty appropriately. Determining the task-specific uncertainty is challenging because of many complex influence quantities that can affect CT measurements. For example, the influence of surface roughness on CT dimensional measurements is discussed in this presentation. The urgent need for international standards and appropriate training and education dedicated to dimensional CT is also discussed.

Title New developments on micro/nano manufacturing science based on evanescent light
In the micro manufacturing field, light energy based production technologies such as photolithography, stereolithography, and various types of laser applied in-process measurement methods have been playing important roles for manufacturing the advanced products. Generally, the spatial resolution of the light energy based technologies is physically governed by the diffraction limit of freely propagating light. That means that the spatial resolution for fabrication or sensing remains limited to approximately half the wavelength of light. We conduct research on advanced light energy based micro/nano production technology, which can be applied to the next-generation micro/nano manufacturing by focusing on special localized photon energy. In order to realize our target, not only conventional light energy propagating in free-space but also localized light energy emerging at near-field region of bulk material like evanescent light is applied as manufacturing techniques.
In this talk, I would like to present the challenges of the spatial resolution improvement of optical fabrication and measurement techniques using evanescent light, which can be generated under a total internal reflection condition. 1) Micro/nano photofabrication using evanescent light energy, and 2) in-process super-resolution high-sensitive optical measurement for nano-defects in semiconductor industry will be introduced and their possibility for the next-generation microstructure manufacturing will be discussed.

Title Plasma-nanomanufacuturing for damage-free dry processing of difficult-to-machine materials
Wide gap semiconductor materials, such as SiC, GaN and diamond, are very promising materials for power device because of their excellent electrical and thermal properties. However, owing to the high hardness and chemical inertness of those materials, and subsurface damage (SSD), which deteriorates the electronic, chemical and mechanical properties of the functional materials, is inevitably formed on the surface in conventional grinding and lapping process. Chemical mechanical polishing (CMP) is widely used in finishing process of SiC, GaN and diamond wafer, but polishing rate of these materials is very low. To resolve these issues, we are now developing plasma-assisted polishing (PAP), which is one of the plasma-nanomanufacturing process proposed by us, to realize highly efficient damage-free finishing of difficult-to-polish materials in dry condition. In the case of PAP, surface of the substrate is modified by irradiation of atmospheric pressure plasma, and modified soft layer is removed by soft abrasive. We apply noble gas (He or Ar) based water vapor plasma for SiC, and apply noble gas based O2 or CF4 plasma for GaN. After the plasma irradiation, surface of the SiC and GaN are oxidized or fluorinated, and hardness of the modified surface is drastically decreased compare to the base material. Softened modified layer is removed by dry polishing using a soft abrasive such as ceria (CeO2) without forming the subsurface damage. In the case of sapphire and diamond, we apply the noble gas based water vapor plasma and oxide plate. Irradiation of water vapor plasma produces OH-terminated surface to both objective substrate and oxide plate surface. Atoms of both substrate and oxide are bonded by dehydration reaction, then the atom of substrate is removed from the surface by motion of the abrasive. In the PAP process, combination of surface modification by plasma irradiation and removal of modified layer by soft abrasive enables us to obtain atomically smooth damage-free surface of hard material efficiently. In this paper, latest research results of PAP for wide gap semiconductor materials are presented, and combined process, which consists of numerically controlled plasma chemical vaporization machining (NC-PCVM) and PAP, for fabrication of high-precision glass lens mold is introduced.
Dr. K. Yamamura started his carrier as a Research Associate at Department of Precision Engineering of Osaka University. He obtained the Degree of Dr.-Eng from Osaka University in 2001.

Title Development of hybrid micromachining processes and machining tool for next generation of micro-products
Micro-machining has attracted great attention as micro-components/products such as micro-displays, micro-sensors, micro-batteries, etc. are becoming established in all major areas of our daily life and can already been found across the broad spectrum of application areas especially in sectors such as automotive, aerospace, photonics, renewable energy and medical instruments. These micro- components/products are usually made of multi-materials (may include hard-to-machine materials) and possess complex shaped micro-structures but demand sub-micron machining accuracy. A number of micro-machining processes is therefore, needed to deliver such components/products.
The talk introduces the concept of hybrid micro-machining process which involves integration of various micro-machining processes with the purpose of improving machinability, geometrical accuracy, tool life, surface integrity, machining rate and reducing the process forces. It takes development of hybrid micromilling and laser bugging process for micro-moulds and laser assisted microgrinding process for ceramic denture as studies to demonstrate the effectiveness of hybrid micromachining process in terms of machining performance and productivity.

Title “Globalization with Digitalisation” – Transformation Strategy of a Chinese Machine Tool Manufacturer
Machine tools are called as “mother machines” . Almost for everything in the world a machine tool is needed at its origin for its production. So far, these equipment is essential for any country which is aiming at industrialization.
After opening to the world 1976 over the years Chinese Government realized that an own capable machine tool industry is necessary for reducing the dependance from foreign suppliers. Several state owned and private enterprices started to produce machine tools. First priority was to satify the demands of local users. As there is an huge market in China these companies became larger without considering export to global markets. On the other hand their technological level was focussed to the average of Chinese users thus the competitiveness in global markets was very limited.
Targeting leveling up the sophistication of Chinese industry as a whole and also improving the competitive position globally Chinese Government declared the machine tool industry as a key industry in Five-Year-Plans.
Shenyang Machine Tool (Group) Co., Ltd. as the leading state owned machine tool manufac-turer realized already early 2000 that for fast closing of the gap between China and developed countries a deep transformation of the company from a state owned, plan focussed company to a market oriented agile enterprize was necessary. Furthermore the management understood that an own CNC control was vital for implementing own features for the easy use of machines as well as for connecting them with the digital world. In terms of mechanical design a close cooperation with german partners was established.
The presentation highlights the transformation procedure of the Chinese company to a global enterprize by utilizing the digitalisation. The experience gained through this precedure should be the guideline for smilar chinese manufacturers on their way to going global and improving the competitive position.
After studying machine tools and manufacturing technology at Technical University of Berlin he worked as scientific collaborator at the Institut for Machine Tools and Manufacturing Technology und Fraunhofer Institut for Production Technology and Design (IPK – Berlin), Chair: Prof. Dr. Spur.

Title Experimental and analytical force analysis in Micromilling
Nowadays micro cutting processes are widespread in several advanced industrial field. However, there is a need of increasing the knowledge on the phenomena involved in these manufacturing processes, in order to continuously improve the quality of micro products and reduce the manufacturing costs. As a consequence, several researchers are incentivised to develop researches aimed to study how the process parameters affect the micro cutting processes in terms of surface integrity (i.e., roughness, residual stresses, strain hardening, corrosion, etc.), geometrical accuracy, cutting forces, burr formation, mechanics of material removal, and so on. Cutting forces play a fundamental role in all machining processes at every dimensional scale (macro, meso or micro). Tool wear, tool deflection, process energy are some of the parameters affected by cutting forces. For this reason there is a relevant number of works and research centre working on this topic. Both experimental analysis and analytical model can be found in literature. A review of these work will be presented in this work together with the results of a research conducted at our University aimed to develop a modelling procedure able to forecast the cutting forces generated during micromilling operations of slots. The presented force model is based on specific cutting pressure and actual instantaneous chip section estimated considering the tool run-out contribution. The model parameters were optimised applying the Particles Swarm Optimization on data coming from experimental tests. Titanium alloy (Ti6Al4V) was considered as workpiece material. The comparisons between experimental and analytical data, and the evaluation of the uncertainty showed the good ability of the proposed procedure in predicting forces in channels micromilling. The developed modelling procedure can be used by industries for evaluating several aspects related to the process such as part quality and precision, failure risks, power consumption and cutting costs.

Title Enabling Technologies for Future Grinding Research
There has been a proliferation in recent years in the range of technologies for supporting research. There is now the potential for a “knowledge and innovation explosion” through the strategic deployment of these technologies. Research into machining processes is indicative where the complex mechanisms and their cause-effect relationships are being revealed by a range of technologies for in-process sensing, offline and “in-laboratory” measurement and characterisation. Moreover, there is now the potential for interconnection of data from sensors and instruments “to the cloud”, enabling advanced data analytics and autonomous learning.
On the other hand, the complex mechanisms in grinding processes are also more easily elucidated and simplified by the minimisation of experimental “noise” in the machine-process. In particular, advances in machine tool technologies reduce inherent sources such as extraneous vibrations, by the design of high stiffness machine tool structures. Machine tool technologies will also, now and in the future, contribute to the scope for process improvement and overall optimisation by providing more control functionalities such as; new control parameters, multi-mode control and intelligent tooling. The present contribution describes some of these developments with due regard to general and specific goals of research and optimisation of grinding processes. It will consider the possibility of setting out a general strategy for expediting process research and development in the context of more rapid technological change and trends such as mass customisation.
Dr Ahearne is a Professor of Manufacturing Engineering from University College Dublin (UCD) in Ireland.
