Příjemce : FUNDACION TEKNIKER
Anotace : In the manufacturing industry, the machining of medium and big size parts with the required and suitable precision is a challenge, especially in high added value products manufactured in small or single-unit batches made of high performance materials like in aeronautic, space or energy sectors, where conventional process engineering and test/error methods are not completely efficient.INTEFIX aims to increase the performance of the machining processes by the use of intelligent fixture systems, allowing the monitoring, control and adaptation of the process to obtain suitable results according to precision, quality and cost requirements.The main outcome of INTEFIX project will be the integration of new and state of the art technologies (sensors, actuators, control algorithms, simulation tools...) applied to the workpiece handling systems to develop intelligent and modular fixtures capable of modify the behaviour and interactions between the process and systems in machining operations; reducing time and costs with improved performance and capabilities.The proposed intelligent-modular fixture is a step forward to the smart manufacturing, providing new features of automation, flexibility, versatility, cost-efficiency and accuracy to the current, state of the art, manufacturing systems and equipment.The intelligent fixture will provide sensors and active drives to obtain a suitable fix of the component modifying the force and position of active locators and clamps, in order to select the suitable static and dynamic behavior of the machine-fixture system for improving the process (setup, deformations, vibrations...). This implies a fast-reliable connection and data transfer between the different ICT systems (CNC, PLC, sensors, actuators, CAD-CAM...) using ad-hoc methodologies and software.Furthermore, the use of modular elements eases disassembling and reuse of the advanced components improving the flexibility and sustainability of the manufacturing process.

Anotace : Lightweight components are gaining in importance in EU key industries with good market growth potential (aerospace, automotive, power generation, medical technology etc.). To achieve weight reductions, complex thin-walled structures are combined with high strength materials. However, the lower stiffness of work pieces leads to severe challenges during the milling process: - Difficulty to achieve high work piece quality, due to vibration and process forces, in industries that have very high safety and quality requirements (aviation, space etc.). Therefore, in many cases manual finishing of the work pieces is required. - Achievement of acceptable work piece quality only through time and resource consuming trial and error identification of process parameters that circumvent critical process states. This often results in slow and inefficient processes. To overcome these problems, DynaMill aims at achieving the complete control over the milling process of thin-walled work pieces. This will be realised through a threefold approach combining the development of process planning, adaptive clamping devices and improved cutting conditions. Subsequently, these three developments will be integrated in the DynaMill Technology as a platform. Throughout the project demonstration of intermediate and integrated solutions will play an important role. The concrete impacts for industry include: - 30% reduction of production time and costs - 80% increase in process stability - 30% reduction of power, compressed air and coolants - 60% reduction of process set-up time and 70% reduction of wasted raw materials during set-up - 20% improvement of tool life - Elimination of finishing operations As a result the competiveness of European industry will be enhanced significantly. For the project, a strong consortium consisting of two research institutes, four manufacturers of key technologies (CAM software, machine tools, clamping devices and tools) and four end users has been gathered.

Výzva : FP6-NMP - Nanotechnologies and nanosciences
Příjemce : FUNDACION FATRONIK
Anotace : The ECOFIT proposal addresses as general objective a drastic reduction of the mass of machine tools for production systems (around 70% for structural components and motion units) and, consequently, a reduction of the energy consumption (around 30% less) fo r the use of these new type of machines. ECOFIT represents a radically new approach to industrial machinery conception, aiming at the development of a radically new technology for cleaner and more efficient production, by means of a paradigm shift: changin g from current stiff and massive machinery, with high energy consumption, to lightweight elastic machines with controlled flexibility and thus much lower enrgy needs. This new approach of "lightweight elastic machines with controlled flexibility" represent s an important novelty regarding the way production systems are conceived. It is estimated that currently, approximately an 80% of the total mass of a machine tool is used to stiffen the machine for accuracy purposes, whereas only the remaining 20% is used to fulfil the kinematic requirements of the machine. With the aim of approaching this separation between mechanical stiffness and accuracy in machine tools, this project will combine mass reduction strategies in combination with new control strategies ba sed on damping considerations and new optical servoing solutions. The cornerstone of this new machine conception philosophy is that accuracy will be achieved by mechatronic stiffness against disturbances and external perturbations instead of using mechanic al stiffness to achieve that robustness. This project will reach the frontiers of current knowledge by the synergetic combination of new eco-design methodologies, innovative robust controllers for the flexible mechanism systems, optical servoing and smart materials featuring distributed actuators and sensors to the flexible components. This new approach will be exploited by the proposing industrial companies, builders of machine-tools, of piezo-actuators
