Texto completo da fonteLes machines de fabrication additive métallique actuelles sont dispendieuses et généralement peu productives. De plus, la plupart des pièces issues de la fabrication additive doivent être usinées après l’impression pour obtenir de bonnes tolérances géométriques. L’objectif de ce projet de recherche est de développer un système de fabrication additive hybride pouvant remplacer les machines d’usinage traditionnelles. Les systèmes hybrides combinent les avantages de la fabrication additive et de l’usinage dans un seul système. Ce mémoire présente le développement et la mise en service d’un système de fabrication additive hybride formant des pièces en aluminium à partir d’un filament d’Al4043. Ce système utilise une technologie innovatrice qui se base sur le principe de chauffage par induction. Le filament est fondu directement par induction à l’intérieur d’un tube, puis un flux d’argon permet à l’aluminium en fusion de s’éjecter du tube. Cette méthode permet de faire des préformes en aluminium qui peuvent être usinées afin d’obtenir une pièce finale. Cette technologie permettrait de fabriquer une machine hybride à faible coût tout en ayant un taux de déposition élevé. Le système a été installé sur un bras robotisé FANUC. Les résultats préliminaires démontrent qu’il est possible de générer des gouttelettes d’aluminium de manière contrôlée en pulsant le débit d’argon grâce à une valve. Les gouttelettes sont générées à chaque pulse puis sont projetées sur un substrat en suivant une trajectoire précise. L’accumulation des gouttelettes formera une couche d’aluminium, puis les couches seront empilées pour former une pièce. Des pièces en aluminium ont été mises en forme grâce à ce nouveau procédé de fabrication additive. Le volume des pièces pouvant être imprimées est limité par la perte d’efficacité du système de chauffage par induction après plusieurs minutes d’utilisation. La densité apparente la plus élevée obtenue avec ce système est de 84%.
Current metal additive manufacturing machines are expensive and generally unproductive. In addition, the majority of parts from additive manufacturing must be machined after printing to achieve good geometric tolerances. The objective of this research project is to develop a hybrid additive manufacturing system that can replace traditional machining machines. Hybrid systems combine the benefits of additive manufacturing and machining into a single system. This thesis presents the development and usage of a hybrid additive manufacturing system that can form aluminum parts from a Al4043 filament. The system presented in this thesis uses an innovative technology that is based on the principle of induction heating. The filament is melted directly by induction inside a tube, then a flow of argon allows the molten aluminum to eject from the tube. This method makes aluminum preforms that can be machined to obtain a final piece. With this technology, it could be possible to manufacture a hybrid machine at low cost while having a high deposition rate. The system was installed on a FANUC robotic arm. Preliminary results demonstrate that it is possible to generate aluminum droplets in a controlled manner by pulsing the argon flow through a valve. The droplets are generated at each pulse and are projected onto a substrate along a precise trajectory. The accumulation of droplets will form a layer of aluminum, then the layers will be stacked to form a part. Aluminum parts have been shaped by this new additive manufacturing process. The volume of parts that can be printed is limited by the loss of efficiency of the induction heating system after several minutes of use. The highest bulk density obtained with this system is 84%.

Texto completo da fonteThe aim of this works is to define a design methodology of hybrids casting molds. This methodology is based on technical and economical limits of conventional process and 3D sand printing. Firstly, these limits were evaluated by mechanical and dimensional characterization of 3D sand printing molds. Mechanical characterization was realised by three points bending test and compression testing with different parameters. 3D printer dimensional capability was determined by samples measure printed in different directions. Secondly, the design method of conventional molds was established from smelters know-how which are ANR MONARCHIES project partner from different case study. Inherent design rules of sand 3D printer were defined from the ITHEMM laboratory research works and completed with parts studies. 3D printing molds design process was created by design rules and validated with studies cases. Manufacturing cost of printing molds was defined by analytic and parametric method. The hybrids molds design methodology relies on all previous works and on complexity index. Optimal manufacturing process for different molds parts was selected according to the complexity index value, mould assembly restraint and manufacturability cost. Finally, this methodology was tested on representative sample group of casting parts, allowed to evaluate the robustness

Texto completo da fonteThis work focuses on the establishment of microstructures and the characterization of the mechanical properties of Inconel 625 alloy produced as part of the PAM-PROD project aimed at producing large parts using high deposition rate additive manufacturing. Three deposition techniques are being studied: Arc/Wire, Laser/Wire and Laser/Powder, as well as a combination of Laser/Wire and Laser/Powder to produce a hybrid wall. Macrostructures and microstructures are characterized for each process. The Arc/Wire and Laser/Powder processes used lead to a mixed columnar - equiaxed macrostructure. The Laser/Wire process leads to predominantly columnar structures. Mechanisms for the formation of columnar/equiaxed structures and transitions are proposed. These mechanisms are then taken up and completed to interpret the formation of the transition zone in the case of a hybrid Laser Wire/Powder wall. The response to solution heat treatment and ageing is then presented by detailing and comparing the kinetics and mechanisms specific to each process. The tensile mechanical properties along 3 directions are then characterized and related to the structures. For all the processes, a high degree of reproducibility is obtained and none of the processes has a brittle character. The best properties were obtained with the Laser/Powder process, and the hybrid junction test showed that the transition zone was not a weak point in the structure

Texto completo da fonteNew needs in the field of satellite telecommunications have led manufacturers in the sector to focus on optimizing resources by creating reconfigurable systems able to adapt their operating frequencyplan during the mission. This thesis focuses on multiplexers and how to make them agile through their architecture and the filters that compose them.This manuscript starts by realizing the state of the art oftunable filtering devices through analysis of contributions made by research teams around the world. Based on this state of art,solutions to the problematic are proposed using a hybrid coupler multiplexing topology. Then studies are presented on various tunable cavities or coupling elements concepts. Some of these concepts have been selected and assembled to form tunable filtering and multiplexing functions. The last part thus presents two tunable multiplexers, allowing narrowband or broadband reconfiguration. An experimental realization has also been conducted on the narrowband version

Texto completo da fonteSouth Africa is constantly loosing contracts for the manufacturing of innovative projects to the East, due to its non-competitive mould-making industry. The paper will report on progress made in a specific focus area in mould-making, namely Hybrid Moulds for injection moulding. Hybrid Moulds refers to a hybrid between Additive Fabrication and conventional methods through the use of amongst others, Direct Metal Laser Sintering techniques, combined with conventional CNC machining (High Speed) techniques. Although the emphasis is on an economically viable process for limited production runs, once the moulds have been developed, it normally is pushed to its limits to realize production quantities. One of the competitive edges is the cutting of lead-times, which obviously impacts on production costs. Another aspect is the ability to manufacture short runs of injection moulded parts in the required engineering material Realising that Laser Sintering of metals is an expensive manufacturing process, a concurrent manufacturing process was developed. Intricate mould details, which normally are time-consuming to manufacture through EDM processes, were grown as inserts, while the less-complex parts of the mould is machined in Aluminium through 3 and 5 Axis High Speed CNC Machining. Using a 3-axis CNC wire cutter, pockets will be created where the more complex Laser Sintered Metal inserts will be fitted. One of the competitive edges is the cutting of lead-times, which obviously impacts on production costs. Another aspect is the ability to manufacture short runs of injection moulded parts in the required engineering material.

In recent years, three dimensional (3D) printing is the fastest growing technology. Nowadays, it has been largely applied in aerospace industry, industry and medicine engineering, etc. Additive manufacturing (AM) technologies not only reduce the new product development cycle, but also develop unique style models to satisfy users’ requirements. However, the additive manufacturing cannot complete the diversity and complexity products independently. We design the hybrid 3D printing machine including the additive and subtractive processes to complete the products. And the products may be composed of the many parts or objects. In the common slicing software, the 3D printers print an object layer by layer. However, when multiple objects are printed at the same time, the nozzle moves among objects and always increases enormous distance of the transition travel. Therefore, in this thesis, we propose a novel addition process optimization algorithm and develop the trajectory planning of the subtractive process to carve the customized logo or image. In the beginning, the optimization of the addition process is divided into three main steps. 1. The optimization for locating each specific object is implemented to minimize the supports during the printing procedure. This step can efficiently save the materials and consume less time for remove the supports. 2. Two dimensional packing problem for planning location of multiple objects is combined with the traveling salesman problem to promote the spray efficiency of nozzle. 3. With consideration of the workspace and hardware limitation, the printing time is apparently decreased by addition path optimization. Compared with the common path planning strategy, the advantage of the proposed path planning minimizes the frequency of movement among each object. This proposed algorithm effectively decreases time consuming on printing and saves energy consuming furthermore. For subtractive process, the object information can be obtained from additive process and is transformed to subtractive coordinate system. The sculpture region of the 3D object is initially expanded into 2D space by conform mapping, and the vertices of the flattening plane are adjusted to appropriate positions using spring mass model with edge-based flattening algorithm to minimize distortion of flattening plane. Then the 2D image can be intuitively projected onto the expanded plane by geometrical transformation. The projected product in 2D space can be reversely transformed into 3D space, where the reconstructed surface is fitted onto the original surface of the object. Therefore, the subtractive part can run along the path that is generated by above steps. We have demonstrated the success of the proposed methods by using the development of hybrid 3D printing machine consisting of additive and subtractive processes in our NTU robotics and automation lab.
