Mechanical engineering

Trajectoire adaptative pour fabrication additive utilisant une source laser

The invention relates to a method (P) for determining the path followed by a selective additive manufacturing laser beam of a three-dimensional object, the laser beam being intended to be emitted to a layer of powder and moved along a path…

Mechanical engineering

Influence of the opto-mechanical chain on the energy provided by the laser spot to the material in laser powder bed fusion processes

The additive manufacturing machines used in laser powder bed fusion processes are composed of an opto-mechanical chain whose purpose is to focus the laser in the work plane to locally fuse the material with the required energy. The opto-mechanical…

Mécanique

Une approche d'inspection 3D automatique combinant capteur laser et palpeur

La mesure multi-capteurs s'avère très attractive pour la métrologie dimensionnelle, car elle permet un gain de temps certain. Cependant le gain de temps n'a de sens que si la qualité des résultats respecte le besoin métrologique. En effet, les…
