Today, the rapid advance of additive manufacturing, namely 3D printing, gives options and capabilities to simplify the fabrication of three-dimensional complex structures. In fact, such technology brings a real rupture comparing to conventional technologies in terms of design and manufacturing. Taking those advantages, this paper presents the desig...

In this paper, we propose a SysML model and a Modelica simulation of an air-jet conveyor for micro objects. Indeed, modeling and simulation are part of verification & validation activities, which are important tasks during the conception of a complex system. This article focuses mainly on the modeling and simulation of air-jet nozzles and on their...

In this paper we consider microfactories for manipulation and assembly. These microfactories are composed of several cells containing microrobotic systems capable of a high level of repeatability. The assembly plan of the production is a pipeline of tasks that are performed by the cells. Our aim is to manage the production flow in the case where th...

The construction of a new generation of MEMS which includes micro-assembly steps in the current microfabrication process is a big challenge. It is necessary to develop new production means named micromanufacturing systems in order to perform these new assembly steps. The classical approach called “top-down” which consists in a functional analysis a...

As no reliable methods is available to manipulate component whose typical size is up to 100μm, current industrial assembled products contained only components down to this physical limit. In that scale, micro-assembly requires specific handling strategies to overcome adhesion and high precision robots. This paper deals with an original robotic syst...

La fabrication automatisée de microproduits requiert lors du prototypage une assistance technique à l'opérateur compte tenu de l'inaccessibilité directe que ce soit pour agir ou pour observer et mesurer. L'instrumentation des plateformes devient incontournable et l'interopérabilité des modules requiert une architecture adaptée du système d'informat...

Microfactories are new specific and flexible systems to produce and assemble micrometric products. These systems are different of standard production platforms because they are confronted with a lot of constraints without influence at human-scale systems. This approach will lead to the development of an architecture of the technical information sys...

les microsystèmes de production ont la dualité d’opérer dans l’univers particulier du micromonde et de constituer un système de production à part entière. Ainsi, ils ont la nécessité de pouvoir s’intégrer dans un milieu fondamentalement différent de l’échelle humaine. De plus, il leur faut assurer un certain niveau de productivité, de flexibilité e...

The development of new hybrid microsystems needs new technologies which are able to perform assembly of small micro-objects. Now, the current micromanipulation technologies are still unreliable for micro-objects which typical size is down to hundred micrometers. Consequently, the study and the development of innovative artificial micro-object manip...

The increase greater than ever in the developments of microproducts leads us to consider the design of an automatic, flexible, reconfigurable and upgradeable microfactory. Thus defined, the microfactory has the ability to implement an infrastructure of automated manufacture in small or average batches, and will be able to prove the feasibility of a...

This paper shows, in a global solution of the control of a microfactory, a dedicated and perennial structure of a technical information system. Our objective is to allow the realization of a reorganizable and reconfigurable production microsystem. The manufacture framework is located in the production of small and medium batches of different microp...

Aujourd’hui, on trouve des microproduits dans de nombreux domaines : médical, son, image, constituants de l’automobile, électroménager. De nouveaux appareils de production adaptés doivent être développés pour répondre à une fabrication bien particulière et une demande en forte croissance. Dans le soucis d’intégrer à la fois des contraintes fonction...
