In this study, a real-time collaborative 3D assembling system (Co-assembler) has been described that allows casual customers to interactively and virtually configure the 3D products over the Internet. It provides a framework for a web-based 3D assembly system that uses a customizable product model to significantly simplify the configuration and the assembly process, and a customer-driven recomm...

in this paper, we introduce ergonomic system in assembly department of irankhodro as a case study, and then we measure its role in employees’ health and improving efficiency and productivity. to this end, we studied the effective factors including environmental, physical, safety, mental, psychological, and training. this research is descriptive – applicative in nature. data were collected throu...

We have developed a semi-automated assembly system and constructed 124 silicon microstrip modules so far for the ATLAS SCT barrel. This article describes the assembly procedure, evaluations of precisions and the module survey results. A precision of B2 mm is achievable with this assembly system. r 2003 Elsevier B.V.

The alignment procedure is an important step in the process chain of the assembly of micro-optical components and has a direct impact on the system performance of the micro-optical system, the necessary assembly time and the manufacturing costs. For these reasons, only alignment procedures that are adapted to the special requirements of each assembly task will be able to save costs and attain t...

Challenges facing the scaling of microelectronics to sub-50 nm dimensions and the demanding material and structural requirements of integrated photonic and microelectromechanical systems suggest that alternative fabrication technologies are needed to produce nano-scale devices. Inspired by complex, functional, self-assembled structures and systems found in Nature we suggest that self-assembly c...

Assembly sequence design for a mechanical system can have significant impact on manufacturing cost and product quality. Traditionally, such a design process is largely based on experience and best practices, often ineffective and non-optimal as the system becomes complex. This paper proposes a new, systematic method for automatic assembly sequence design and optimization. Key elements include a...

This paper proposes a flexible assembly system that manages production by negotiating with autonomous manufacturing devices. With this mechanism, physical layout of the system is independent of the type of products to be assembled, and the system can asynchronously process multiple parallel production tasks. This system also supports Plug & Produce; a system function that enables easy reconfigu...

The paper deal about automated assembly manufacturing cell design. First part is about Methods and techniques used for assembly systems design. Next part describes specific CAD systems used for design process of our assembly cell. With help of this CAD toll we have design geometric disposition of all system elements by CATIA and also parts of control system by FluidSim. Whole design problematic...

A CAD assembly model is a collection of components, comprised recursively of various levels of individual parts and sub-assembly models. Although the overall geometry in the CAD assembly model accurately represents the final finished product, this model is often meaningless from a manufacturing planning and simulation point of view. The grouping of the components into sub-assemblies and the ass...

Micro assembly is typically characterised by positioning tolerances below a few micrometers. In the case of a hybrid micro system assembly, such as optical glass fibres, micro ball lenses or micro probes for measurement tasks, even positioning accuracies in the sub-micrometer range have to be achieved. Due to the need for highly accurate assembly systems and extensive alignment procedures the a...
