Influence of the CNC behaviour on the laser spot trajectory in LPBF process

The quality of the parts produced in additive manufacturing by laser powder bed fusion (LPBF) depends on the understanding of all the physics involved in the process. In LPBF, the effective path of the laser spot is rarely studied and existing works…

Direct additive manufactured beam shape defect identification from computed tomography and modal decomposition

As one of the main additive manufacturing (AM) advantages, lattice structures are being studied in many applications such as vibration attenuation, weight reduction of components or optimised heat exchangers. However, lattice structures are…

A flash-based thermal simulation of scanning paths in LPBF additive manufacturing

During manufacturing by Laser Powder Bed Fusion (LPBF), the laser-scanning path influences the thermomechanical behavior of parts. Therefore, it is necessary to validate the path generation considering the thermal behavior induced by this process to…

Costs analysis of stealthy attacks with bounded output synchronized Petri nets

This paper concerns the security analysis of discrete event systems modeled with a particular class of synchronized Petri nets that include output functions, called Output Synchonized Petri nets. Such a formalism is suitable and tractable to…

Observer Design for Bounded Output Synchronized Petri Nets

This paper concerns discrete event systems modeled with a particular class of synchronized Petri nets that include output functions, called Output Synchronized Petri nets. Such a formalism is suitable and tractable to represent a large variety of…
