Milling toolpath is often designed according to a CAD model which not always an accurate representation of the real part. In industrial framework, significant geometrical variability sometimes observed in parts that belong same batch. Therefore, conventional approach making use unique nominal for manufacturing series fails confer both and dimensional conformity machined parts. This study explores strategy adapting on-line thanks measurements data driven simulation. An approximation actual...
This paper is concerned with the prediction of part distortion induced by residual stress relief during machining. Aeronautical manufacturing requires nowadays production large monolithic parts from workpieces obtained forging or rolling operations. Residual stresses these forming steps are often consequent and represent a significant obstacle for manufacturers. Re-equilibration initial material removal causes to deform.The method presented in this provides tool predicting changes geometry...
This paper proposes a new method for solving the heat transfer equation based on parallelisation in time of computation. A parametric multidimensional model is solved within context Proper Generalised Decomposition (PGD). The initial field temperature and boundary conditions problem are treated as extra-coordinates, similar to space. Two main approaches exposed: “full” an off-line parallel computation “partial” decomposition original problem. Thanks optimised overlapping strategy,...

Abstract In the WAAM process, accuracy of toolpath is prime importance for mechanical properties final part because material defects that could be generated. This paper deals with motion analysis end effector nozzle a robot dedicated to process. The movement create rectangular layer was experimentally analyzed without physically depositing (trajectory definition only). Various strategies, speeds and areas were compared in terms travel time length over different sections order identify...
Real-time control of manufacturing processes is a challenging issue for nowadays industry. The need ever more efficient production requires new strategies in order to make correct decisions an acceptable time. In large number cases, operators working on CNC machine tool have reduced possibilities interacting real-time with the machine. Numerical simulation based that sense appealing alternative conventional approach since it provides operator additional source information, confirming his...
Automated tape placement (ATP) is a process recently developed for the production of large parts (plates, shells) made thermoplastic composites. In ATP placed on previous ply and welded by local heating pressure to build up laminated structure. The numerical modeling such challenging issue since thermal history each different, depending its position within evaluation residual stresses particularly important determining deformed shape piece at end process. A model based Proper Generalized...
Abstract Metal additive manufacturing has been pointed as the answer to reduce time and cost for aeronautic parts with a high buy fly ratio. The manufacturability of part by depends on important indicators that would allow it be effective. One key indicator is time, which highly dependent an factor: interlayer time. needed material cool down chosen temperature, called allows new deposition molten material. temperature defined using time-temperature-transformation (TTT) diagrams, final goal...
Many models encountered in computer science remain intractable because of their tremendouscomplexity. Among them, the numerical modeling manufacturing processes involving severalcharacteristic times is a challenging issue. Classical incremental methods often fail for solving efficientlysuch transient models. In that sense model reduction based simulation appears to be verypromising alternative. Multidimensional parametric can solved within context theProper Generalized Decomposition (PGD)....
Selective Laser Melting offers new perspectives in terms of part design and simplification complex assemblies. However, because such a process is based on the fusion material, severe thermo-mechanical conditions arise are responsible for local plastic deformation, residual stresses distortion manufactured component. Mastering major interest search robust repeatable industrial process. The lack experimental knowledge high cost associated to trial error approach makes it difficult anticipate...
Originally issued from cladding, the LMD-p process widens field of possibilities in terms manufacturing. Depending on targeted application, needs regarding track geometry are different and ability to adapt it is a key challenge. In LMD-p, laser beam attenuation as well powder particles preheating both determined by laser-powder interactions before reaches substrate. The dimensions directly correlated melt pool size: larger will tend capture more resulting higher deposition rate. model...
