Mechanical engineering

Additive manufacturing features definition along with thermal behavior integration

In Additive Manufacturing, features are usually defined in terms of part geometry, with little to no consideration of process physics in either international standards or the literature. This omission represents a major limitation for the…

How task-relevant vibratory feedback from an active exoskeleton can lead to ergonomic postures

In the past decades, active exoskeletons have been dedicated to reducing human effort, in particular to assist workers in occupational environments. However, this approach does not promote the learning of more ergonomic postures by workers, which is…

Superellipsoid modeling of wire-laser additive manufacturing defects measured by digital image correlation

In wire-laser additive manufacturing (WLAM), producing parts with multiple entities requires optimizing both additive and subtractive processes. This involves adjusting positions and integrating machining operations. Geometric defects that occur…

Distributed fault-tolerant control approach for discrete event systems using timed automata with guards: application to an electric power network

Abstract This paper proposes a new distributed Fault-Tolerant Control (FTC) method for discrete event systems based on timed automata with guards (TAGs) and min-plus algebra. The principle is to design FTC for subsystems that are synchronised by a…

Optimizing process stability and energy efficiency in wire arc additive manufacturing of nickelbased superalloys using machine learning

Wire arc additive manufacturing (WAAM) is rising as a key technique in the context of sustainability. In WAAM, single weld beads (WB) are the fundamental entity in toolpath planning. Its characteristics (e.g., height -h, width -w, aspect ratio -h/w,…

Spatters deposition on Inconel 718 laser powder bed fusion manufacturing

In laser powder bed fusion (PBF-LB), the detrimental effects of by-products need attention when defining a manufacturing process. One of the by-products able to modify some parts' attributes is called spatters, which consists of metal particles…
