IMPRESS targets the development of a technological injection moulding platform for serial production of plastic components incorporating micro or nano scale functional features. The platform will be based on the gathering of up to date and most advanced facilities based on three main modules, each of them being a tool box including several building blocks: - a tool manufacturing module involving different technologies of micro- nano direct manufacturing, from top-down to bottom-up such as self-assembling, - an injection moulding module including equipments fitted with up to date hardware to improve replication quality and capability, - an intelligence module dedicated to advanced process control and online metrology integration. Beside this large panel of facilities, three case studies have been selected (biology, health and energy), each of them requiring a specific and well defined surface micro-nano texturation. These case studies cover a very large range of nano-feature (from 100nm up to 1 m) and component size (from 1 cm2 up to 1000 cm2). They will serve to qualify the capabilities of the different building blocks and will allow (i) to select the most suitable building blocks as of application requirements (ii) to learn about the platform working and (iii) to anticipate the technological future of the platform. Finally, a technico-economic tool for decision making will be developed based on the IMPRESS case studies and thus to allow end-users to select the most appropriate configuration regarding the end product manufacturing requirements. Further to the IMPRESS case studies, the performances of the platform will be validated through a satellite group. IMPRESS technological platform will accelerate the production and the time to market of micro nano-scale functional feature on multi-component devices in order to obtain an important reduction of needed supply chain space, technological risk and manufacturing costs of next generation plastic part products.

The proposed project aims at creating new high precision manufacturing technologies to respond cost-effectively and eco-friendly to the mass customization paradigm within the production of complex shape micro parts, embedded systems and miniaturized products at micro/meso-scale level (from 10 to 10.000 micron range). The main objective of Integ-micro is the research and development of new hybrid and reconfigurable multitasking machines and combined processes based on integration of different ultra high precision techniques for the generation of 3D complex shape microcomponents made from different kinds of materials. Multitasking micromachining can be best described as the ability to perform multiple machining operations in one workholding configuration. This guarantees greater accuracy, reduced handling and plant area, faster throughput and increased productivity. The availability of several machining technologies on a single machine allows important synergies between the different machining methods. For instance, combining machining by chip removal and laser micro machine will provide the capability to remove (by laser) the burr remaining from the previous chip removal operation. Alternatively, chip removal machining and laser LIGA technique can be combined in order to machine small components that could not be produced otherwise. The project will bring high added value thanks to the minimum time loss in setting new production lines for strategic products through short reconfiguration time and reduced ramp-up phase. The above goals will be reached exploiting methods of sustainable production, including downscaling of machine size (machine size reduced of 5 times at least), new process chain approaches for dramatically reduced processing times and eco-friendly processes like dry ultra-high speed cutting (UHSC) at micro-meso domain (eliminate the use of cutting fluid to get the target of zero waste emission).

The project ADACOM will address main industrial sectors. automotive (DC, LOLA, CRF), electronics (BOSCH) and printing machine sector (HDM). Next to those OEMs, OEMs supplier and especially sensor manufacturer suppliers (Kistler) will participate in this project in order to reach the following goals: Core development will be an Adaptive Machining Systems for metal cutting operations (milling, turning, gun-drilling, grinding), which consists of a sensor and actuator systems for online manufacturing control related to the part quality. The major aim is to achieve an Online Quality Control systems within the mass production of the above mentioned industrial sectors. In ADACOM this aim will be achieved by separating the single components of such an adaptive machining system into a modularised monitoring system. This modularisation will first of all give the possibility to adapt the different modules in this way that a flexible use of the adaptive system for different machining operations is possible. Next goal of the development within this project will be the realisation of one central system for different processes, which incorporates the flexibility towards changing production situations, different machine tools and different work piece materials. This flexibility of the ADACOM-System will be reached by developing a standardisation of the Adaptive System components. Issues like standardised interfaces, which guarantee Plug and Produce-production, will be achieved by standard data formats throughout the whole production sequence. This implies a connection of manufacture to design and should give the possibility use the same data in the design, production and quality assurance of a mass product.

The objective of HELIOS is to develop a marine low speed two-stroke gas Diesel engine research platform that is realistically sized for direct drive marine propulsion, and that has an emission footprint which compared to present Diesel engine technology is reduced as follows: CO2: 20-30%, NOx: 10-15%, SOx : 90-100%, PM: 60-70%. Since 99% of the world commercial fleet is powered by diesel engines, marine gas Diesel engine technology can greatly contribute to the greening of waterborne transportation. The potential of the HELIOS project is further enhanced by the possibility of retrofit of gas Diesel technology onto existing ships in service, since the needed modifications in components are limited and do not need removal or reinstallation of vessels engine. The research platform will be the basis for a new generation of high pressure gas injection engines operating on compressed natural gas (CNG) and/or liquefied natural gas (LNG), using Diesel type and partly pre-mixed combustion principles. The new generation of engines will be fully electronically controlled and have power ratings from 5.000 to 100.000 kW. The development of a marine gas Diesel engine concept being a realistic alternative to current technology places numerous challenges to the engine designer, ranging from development of reliable gas injection systems, layout of the combustion system including ignition control, engine monitoring, combustion chamber materials. Furthermore the project sets new standards for on board storage and distribution of LNG and CNG. HELIOS addresses all of the above aspects in an extensive R&D enterprise with duration of 3 years. HELIOS will drive forward new technologies, concepts for gas storage, high temperature materials and diagnostics methods, which will also strengthen European companies position as core technology developer and accordingly as know how and hardware provider.

This paper presents the design, fabrication, and characterization of a MEMS actuator with large static deflection as a waveguide-mounted variable millimeter-wave phase shifter. The actuator is composed of a pair of interdigitated microplates actuated by vertical comb-drives and suspended by SU-8 torsional springs. The SU-8 spring possesses a thin metallization top layer and a reverse-T-shaped cross-section enabling low torsional stiffness and high in-plane stability. A maximum mechanical deflection of 10.3° is obtained under a dc actuation voltage of 35 V. The dynamic characterization of the device shows that the resonance frequency of the torsional mode is well separated from the other three bending modes, confirming the designed low torsional stiffness and high in-plane stability. The torsional viscoelastic creeping is measured as a function of time at different loads and shows a maximum of 0.5° for an applied voltage of 27.5 V. A high operation cycle test is conducted and the metalized SU-8 spring withstands 800 million cycles without showing fatigue. RF measurements show that a variable mechanical deflection angle between 0° and 8.2° results in a variable transmission phase shift up to 58.0°. The measured insertion loss is always below 5.1 dB at 98 GHz, corresponding to a figure of merit of 11.5°/dB. © 1992-2012 IEEE.

The authors present an innovative piezoelectric dynamometer (MicroDyn) providing the base for measuring high frequency signals in micro machining operations. Cutting tools with one or more cutting edges used in micro machining processes are mostly running with rotational speeds of more than 100'000 rpm, resulting in high excitation frequency. Thus, the interference of the excitation frequency of those processes with the natural frequency of commercially available dynamometers makes it impossible to measure process forces within a wide frequency range. This paper presents the dynamometer design, results of various laboratory tests and first cutting force measurements taken from high dynamic cutting processes as single grain cutting. © 2012 The Authors.

Many applications such as operational, environmental, structural or durability testing require increasingly more triaxial IEPE accelerometerswith higher frequency operation in the three orthogonal directions. The new, novelmounting for Kistler miniature PiezoStar® and Piezoceramic Triaxial cube accelerometer families offer a practical solution. Additionally, in certain applications that require ultra-low sensitivity temperature coefficient, Piezostar® offers a practical solution when piezoceramic sensors do not satisfy the application needs. The seismic elements of these IEPE triaxial accelerometer families have inherent benefits resulting in high resonance frequency where the sensor design provides stud mounting for each orthogonal axis with threaded holes on three sensor faces. The calibration methodology will be reviewed supporting frequencies up to 20 kHz, without additional mechanical fixtures, which can impact precision measurements. Ultra-low sensitivity temperature coefficient is achievedwith PiezoStar® IEPE accelerometers and will be demonstrated as well as a comparison between more traditional quartz and ceramic sensing elements. PiezoStar® IEPE accelerometers provide less than 1.5 % sensitivity change between -55°C and 165°C, as well as inherent long term stability of a piezoelectric crystal. © The Society for Experimental Mechanics, Inc. 2014.

Products and hence processes for todays manufacturing industry sectors become more and more complex in terms of geometry. Increasing quality demands furthermore prove the need for deep process understanding, product-oriented process monitoring and adaptive control of the machining process. For all of these topics production-suitable sensor solutions are needed, especially the precise measurement of cutting forces. This paper describes the application of stationary force measurement platforms for five-axis milling processes with compensated force signals. The sensor system is developed for the use on a multi axis machining centre and suitable for all processes with non-stationary workpiece axis, e.g.; turning operations and five-axis milling processes. The present paper focusses on the scientific and technical challenges for the develop- ment of an appropriate measurement system for five-axis milling processes. The main technical challenges are the compensation of the dynam- ic forces, the consideration of the gravity force and the changing mass due to the metal cutting process. For this reason, information about the current workpiece position, velocity and acceleration is used for compensating forces that are not resulting from the machining process itself. The compensation of these disturbance forces is executed by means of a suitable, intelligent calibration methodology. Test results on a machine tool in a production environment and the theory for compensation will be presented in this paper. Furthermore, details about the functional design of the system will be provided. © 2014 Published by Elsevier B.V.

Spark plugs with integrated pressure transducer, also called measuring spark plugs, are suitable for measuring cylinder pressure in gasoline and gas engines without the need to provide an additional bore in the cylinder head. Various changes to the original spark plug occur when a pressure sensor is integrated in the body of the spark plug such as the spark position and the maximum diameter of the isolator. This article shows the results that can be achieved in respect of the spark and measurement function on a state-of-the-art, turbocharged, directly-injected gasoline engine with homogeneous mixture operation by comparing the original spark plugs with measuring spark plugs. To this end, various engine operating points were carried out at full and partial load by varying the lambda and spark ignition timing, which were assessed as a reference based on water-cooled pressure sensors. The measuring function as well as the spark function yielded good results where trade-offs had to be made in the threshold areas of the spark timing and lambda variation carried out with respect to the function of the measuring spark plug. These could, however, be due to the changed installation of the ignition coil. Copyright © 2015 SAE International and Copyright © SAEINDIA.
