− De-manufacturing is an entire process of collecting, disassembling, reusing, refurbishing, recycling, and/or disposing products that are obsolete or un-repairable. Designing the products for inexpensive and efficient disassembly enhances the ease of de-manufacturing. Virtual disassembly addresses the difficulty and the methods to disassemble a product in design stage rather than really disass...

Virtual reality is a technology which is often regarded as a natural extension to 3D computer graphics with advanced input and output devices. This technology has only recently matured enough to warrant serious engineering applications. The integration of this new technology with software systems for engineering, design, and manufacturing will provide a new boost to the field of computer-aided ...

The use of virtual reality (VR) in interactive design and manufacture has been researched extensively but its practical application in industry is still very much in its infancy. Indeed one would have expected that, after some 30 years of research, commercial applications of interactive design or manufacturing planning and analysis would be widespread throughout the product design domain. Simil...

As the global competition in the semiconductor industry grows, customer service in addition to manufacturing capability becomes an important way to success. As such, virtual fab (VF) has been proposed by companies in this industry. Taiwan Semiconductor Manufacturing Company (TSMC), one of the world’s largest dedicated IC foundry, constructed its VF to strengthen bond with customers. Customers c...

The Real-Time (RT) class on the Solaris operating system was evaluated to study the feasibility and effects of change in priority and time quantum within an RT class for competing processes. Several experiments were conducted and the results will be compared and discussed in the paper. The application of real-time process control will be discussed in context of a virtual manufacturing environme...

Production process planning in real or virtual environment refers to the choice of parameters and sequencing of certain manufacturing processes with the aim to obtain the required product features with greater productivity, reduced production costs, shorter development time etc. Therefore, innovative systems for virtual process planning, based on intelligent agents, greatly improve adaptation t...

This paper describes the architecture and concept of operation of a Virtual Reality-Enhanced Integrated Process Design Environment (VR-IPDE), a novel architecture for effectively applying Virtual Reality (VR) technology in the context of manufacturing system design. Virtual Prototyping (VP) and Simulation Based Design (SBD) have been used with increasing success in the application of Virtual Re...

Mounting machine is the most critical equipment in the SMT (Surface Mounted Technology), the production efficiency of which affects the entire assembly line's productivity dramatically, and can be the bottleneck of the assembly line if poorly designed. In order to enhance the VM(Virtual Manufacturing) of mounting simulation for PCB(Printed Circuit Board) circuit modular, the virtual reality sim...

Virtual prototyping in manufacturing gains more and more importance, since companies competing in industry noticed the increasing cost pressure alongside higher quality requirements. The utilization of virtual prototyping techniques provides a possibility to reduce the total development costs and the time to market, while simultaneously innovations of both products and processes increase the ov...
