Pełny tekst źródłaHigh mechanical properties of sub-μm grain Al2O3 and 3Y-ZrO2 present high potential for the cutting of wood-based materials. Nine grades were produced by gelcasting (GC) and cold isostatic pressing (CIP). They were tested in real industrial conditions. From those results, this thesis’ aim was to highlight the wear mechanisms in cutting, and then deduce major physical and mechanical properties that are task of material development. Consequently, prototypes for cutting trials have been developed. As a result, the manufacturing of prototype tools, X-Ray diffraction, analytical and numerical investigations were performed to quantify residual stress that occurred in ceramic. Observation of the results of experimentations in machining showed different wear modes. For alumina’s grade, single grain pull-out was the main wear mechanism of the cutting edge, while microplastic deformation occurred in zirconia’s composition. Physical properties of ceramic structure, like grain size and density, are more important than mechanical properties. To improve cutting lifetime, density must be higher than 99%, with a structure with sub-μm grain size. It appeared that there was a predominant role of micromechanical stability while cutting abrasive materials. Fracture toughness or thermal shock resistance seem to have marginal influence when ceramic were produced by low-defect process like GC. Regarding all ceramic grades the Al2O3-10ZrO2 made by GC showed the highest wear resistance in machining. Unstabilized zirconia brought micromechanical stability between grains of the cutting edge while working

Pełny tekst źródłaThe presented work consists to improve milling process of sculptured surfaces. The aim is to reduce disturbances during machining in order to obtain a better surface roughness without increasing the manufacturing time. The study was conducted in 5-axis milling for torus cutter with round inserts suitable for the considered parts. The first part of this study establishes a cutting force model with a tool axis inclination towards the back of the tool. It leads to a formulation to balance the transversal cutting force that brings a significant improvement on tool dynamic behaviour. The second part presents a free gouging tool positioning and an associated strategy using the balance of transversal cutting force. The proposed method is globally validated on a complete example of sculptured surface machining

Pełny tekst źródłaDeep drilling (Drilling distance >= 5 x Øtool) with BTA system (Boring Trepanning Association) occurs when you produce parts with good productive performance combined with good machining quality. Mechanical industries operate in a context of constant competition, with ever greater technical and economic requirements. This study illustrates the desire of many industrial players (AREVA and CIRTES) and university (LEMTA, Université de Lorraine), to advance in the understanding of machining mechanisms that govern this process. A literature review revealed that this technology offers a vast and relatively unexplored field of investigation and study. The aim of this study is to analyze and modelling the phenomena which occurring in a deep drilling operation. An analysis of the morphology of the chips has introduced a new parameter for assessing the mechanical stresses suffered by the material being machined . The proposed approach allows to define the mechanical stress torsor by integrating the real cutting geometry, for all cut surfaces of active drilling head BTA. The principles of modeling used allow a relatively easy application to many materials and from the identification of a minimum parameters. Original experimental methods have allowed the identification of parameters and adjust and examine the validity of modeling. The limitations of the law of behavior have been used in evidence, and the prospects for further studies have been proposed. Nevertheless, all the results of this study open, modestly, interesting perspectives, especially in the field of helping for the choice of optimum cutting parameters, and help in the understanding of the physical phenomena of the cut

Pełny tekst źródłaDue to their high hardness and wear resistance, cemented carbide (WC-Co) is the main material used to manufacture machining tools and forming tooling, as well as wear parts requiring high hardness and high precision. The modification of tungsten carbide microstructure, and more particularly its cobalt content, is currently attracting the greatest interest from manufacturers to develop new grades tools with high performance, and then expand new markets.This thesis aims to study the effect of the cobalt content of carbide tools on the measured values and wear mechanisms when machining hard superalloys such as the aeronautical titanium alloys Ti-6Al-4V. Both experimental and numerical research work are devoted on one hand to the understanding of the microscopic damage mechanisms leading to the macroscopic wear of the WC-Co composite and on the other hand, to the influence of the cobalt content on the behavior of the WC-Co taking into account the mechanical-microstructure-damage coupling.On the basis of an experimental analysis, the identification of the macroscopic and microscopic physical phenomena involved at the tool/chip and tool/workpiece contact interfaces was conducted. Machining tests were firstly carried out on the tool-material couple WC-Co/Ti-6Al-4V with different cobalt contents for the tools (from 6 to 15%). In a second step, a tribological characterization of the same tool-material couple was carried out to evaluate the influence of the cobalt content and the contact conditions (sliding speed, applied force) on the friction coefficient and wear. However, the inaccessibility of the contact zones during machining and the tribological tests did not allow a complete description of the wear mechanisms observed, whether macroscopic mechanisms (adhesion, abrasion, deformation, ...), or microscopic mechanisms (cracking, damage of the WC and Co phases). The numerical simulation using finite elements (FE) proved to be a very interesting complementary tool for the analysis of these wear mechanisms.Our modeling strategy focused on the response of WC-Co at the microstructure scale for the thermomechanical loading close to that obtained by machining. The proposed model takes into account the behavior of the WC and Co phases separately and that of the interfaces WC-WC and WC-Co of the composite. This strategy allowed to study and identify parameters influencing the behavior of the microstructure from the elastic stage to the damage initiation. A good agreement was obtained between the results of the numerical behavior at the initiation of damage in the microstructure and those of the experimental observations in terms of the effects of the cobalt content in the tungsten carbide and of the applied machining conditions

Pełny tekst źródłaAeronautic composites are inhomogeneous and most often consist in two distinctly phases. The reinforcement fibres are relatively hard and brittle whereas the matrix is soft and ductile. The anisotropy causes some severe challenges when machining composites. People in the field often experience a trade-off between two main problems ; on one hand, keeping the composite parts integrity and quality, and on the other hand, reducing the wear of the cutting tools. The quality level required in aeronautic applications imposes a high quality cut of machined parts. Common defects that may occur during machining of these materials are delamination, overheat of the resin, uncut fibres, and fibre pull-out

Pełny tekst źródłaProduction equipment has undergone significant technical developments in recent decades. The current trend is to minimize the number of setups required to machine a part in order to improve the cycle lime and accuracy. The screw rnachining industry is heavily subject to the problem of meeting increasing production volumes under stronger customer requirements. Unfortunately, methodological tools and software packages have not evolved at the same pace and the indus-trialization of parts of increasing complexity remains a serious problem. However, "academic" in- dustrialization methods do exist, but they were initially designed for conventional part machining out of plots of material and are not adequate when machining parts out of bars, which is the main characteristic of screw machining. The flow method presented in this thesis tackles this problem by providing a systematic approach to the methods technicians, enabling them to sequence the different manufacturing operations into a minimum number of steps and thus; a minimum number of machine halts. To do so, we propose a formal description of the manufacturing process, organizing it in work stations, setups and manufacturing operations. We then propose to organize the manufacturing operations in steps intended either for the initial or periodical setting up of machines, or for their monitoring in production. The creation of a different setting up plan than the monitoring plan seems essential and is consistent with the fact that the setting up and monitoring of machines are often carried out by two different persons in industry, in this case, a setter and an operator. For each of the plans, we determine a set of working dimensions through an innovative approach called the "chain of dimensions of minimal measurement uncertainty". To this set of working dimensions, we propose to add a new set of dimensions that we call "pilot dimensions". These correspond to the parameters on which the operators can act upon in order to correct working dimension deviations. A spreadsheet is then generated for the operator. This spreadsheet will provide the operator with the corrections that need to be carried out on the pilot dimensions based on the deviations measured from the working dimensions for each step of the setting up or monitoring process. Experiments on industrial cases have helped us to validate our approach which has been implemented in an industrialization software package called Copilot Pro®. This research program is the result of the collaboration between the SYMME laboratory of the “Université de Savoie” and the “Centre Technique de l'industrie du Décolletage”, and is also part of the “Tolérancement et Qualité des produits” program of the “Pôle de Compétitivité Arve-Industries Haute-Savoie Mont-Blanc”
