Texto completo da fontePour remédier à ce phénomène en tournage des matériaux, une étude expérimentale originale exploitant la notion de torseur d'efforts est mise en place pour déterminer, très précisément, le comportement dynamique du système usinant (pièce/outil/machine). Les principaux paramètres relatifs au comportement dynamique du système usinant sont identifiés. La localisation des déplacements de la pointe de l'outil dans un plan caractéristique est démontrée. L'existence de ce plan et les corrélations avec les caractéristiques élastiques du système usinant permettent de simplifier le modèle dynamique 3D et de proposer un modèle en accord avec les résultats expérimentaux tout en restant dans une configuration tridimensionnelle de la coupe.
La simulation numérique issue de ce modèle simplifié fournit des résultats en bon accord avec l'expérience.

Texto completo da fonteThe process damping results from the interference between tool clearance face and the workpiece generated surface and affects the stability of a machining process. Therefore it is necessary to take this phenomenon into consideration during the simulation of machining process. This thesis work presents a practical method for identification, modelling, and numerical simulation of process damping during machining of a workpiece. A special fixture has been used which creates the vibrations conditions necessary to generate the interference between tool clearance face and the specifically designed workpiece. The modelling of process damping is based on the numerical calculation of the interference volume between tool clearance face and the workpiece generated surface. The tool and workpiece geometries are represented by z-buffers whose relative positions at each instant permit to evaluate numerically the interference volume. The process damping coefficients are then estimated by minimization of the error between measured cutting force and the simulated cutting forces

Texto completo da fonteVibrations assisted drilling is a process which ensures chip shape control in order to increase reliability during drilling operations. The adding of axial oscillation, controlled with amplitude and frequency, introduce two new parameters which must determinate according to the conventional parameters (feed and speed rotation). The optimal setting of vibrations assisted drilling is not obvious. To provide an optimization-tool of the process, a new model which take into account the “Tool-Workpiece-Machine” environment, is proposed. Drill geometry, Tool-Workpiece interactions and dynamic behavior of the Machine are incorporated in the model. Tis specificity allows adjusting behavior of the process with the case of application. An identification methodology is presented to characterize the environment. Simulation’s results and experimental results are compared to validate the model. This model thus allows predicting process behavior in order to optimize the operational parameters

Texto completo da fonteThe optimization of the cutting parameters in high-speed machining requires the consideration of the machining errors in the modeling of the cutting forces and the surface topography. Therefore, the present study deals with the analysis of the effect of cutting parameters and machining errors on the surface topography of milled surfaces with a ball-end mill. The tool geometry was modeled taking into account all the machining errors such as runout, bending, vibrations and wear. Then, the Cutter Workpiece Engagement region 'CWE ', the cutting width and the uncut chip thickness were modeled taking into account the trace of the previous tooth. Subsequently, thermomechanical modeling of cutting forces in the milling process with a ball-end tool is made considering these errors. Finally, an analysis of the topography according to all these parameters and machining errors was carried out based on experimental validation

Texto completo da fonteIn this study, we are interested in a machining production system which is one of the manufacturing processes most adopted by the various mechanical industries (automotive, aviation…etc.). The objective of this multidisciplinary thesis (Mechanics and Industrial Engineering) is double: (1) the development of a new thermomechanical model of oblique cutting in dry machining and (2) the maximization of profit in order to establish a strategy production and a preventive maintenance plan.The coupling between the machining operation and the part "simultaneous optimization of production and maintenance costs" is done by considering the effect of cutting conditions on the generated surface quality and on the tool wear. In the proposed approach, wear is taken into account through Taylor's empirical law and the machined surface quality is predicted via a new model of vibrations in oblique cutting.The first objective of this work concerns the development of a new thermomechanical model of the oblique cutting with vibration. In this analytical cutting model, the vibratory system is assimilated to a system with a single degree of freedom in the tool feed direction. We take into account the coupling between tool oscillations, the thermomechanical process of chip formation as well as the regenerative effect. The latter results from the variation in the material quantity to be machined between two successive passes. The coupling between all of these mechanisms makes the problem to be solved strongly nonlinear. A resolution algorithm making it possible to reduce the computation time has been implemented.The second objective of the thesis is achieved through the development of an analytical model where the optimization consists in maximizing a profit integrating selling price of finished product, production and maintenance costs. We note the originality of this part consists in considering the impact of the machining conditions, especially the cutting speed, on the production durations and costs, the quality of the machined parts as well as the degradation of the production system. The impact of machining conditions on three fundamental aspects is therefore considered simultaneously for the "simultaneous optimization of production and maintenance costs" part. The first concerns the impact of machining conditions on production time and costs. The second concerns the impact on the degradation of the machining system and therefore on the optimal maintenance plan to be adopted. The third concerns the impact on the quality of the output product which directly affects the selling costs and more specifically the total profit. These interactions are taken into account through the development of an analytical model to establish an optimal integrated production maintenance plan for the machining system, illustrated by the optimal switching date for changing cutting speed and the optimal numbers of batches to produce before every preventive maintenance action for every production phase. Every production phase is characterized by a cutting speed

Texto completo da fonteThe main objective of this project is furnishing information to clarify the vibrations physics in machining from orthogonal cutting. First chapter contains the machining process characterisation by means of cutting forces. We evaluate the piezoelectric dynamometers in frequency domain and the influence of assembly components. These evaluations reveal the dynamic measurements problems. At the end of this part, we propose a correction method of piezoelectric dynamometer measurements to frequencies higher than dynamometer bandwidth. Also, we present an application of the method. Second chapter comprises the understanding of vibration sources. We analyse specially the segmented chip formation because its excitation role is not clear in literature. Also, we consider the effects of regenerative excitations, which depend of interaction between cutting conditions and machine-tool dynamic response. Third chapter includes the experimental identification of vibration sources during machining. We have identified and characterized the segmented chip formation and the machine-tool dynamic
