Post industrial technologies have improved human standard of living, however, a host of negative environmental consequences from the unlimited industrial appetite have posed serious global challenges. Remanufacturing is an industrial manufacturing process that is to restore old products to perform like a new and to save energy, natural resources, landfill space and to reduce air pollution by less re-smelting. By extending product lift cycle, remanufacturing gives us enormous opportunities for sustainable development of our society. This paper introduces needs and current state of the art in the field of remanufacturing, also analyzes old products in terms of product variety and wear conditions with an example of automobile alternators. Then, a general and a product-specified remanufacturing process will be determined with them. Finally, this paper shows systemized guidelines for remanufacturing process of the specified parts. The results could be also used as a basic information for further remanufacturing applications.

최근 환경문제를 고려한 디자인의 방향은 '생태적으로 균형된(Eco-Balancing)' 방법이어야 한다고 공감하고 있다. 이는 제품의 생산, 유통, 소비, 폐기의 전 과정에 걸쳐 발생되는 에너지 소비, 재활용도, 오염도, 폐기문제 등의 총체적 개념에서 재료와 생산방법을 평가하고, 이를 디자인 문제해결의 초기 단계에서부터 적극적으로 고려하는 확대된 개념으로 변화된 것이다.(중략)

To save time and cost in assembly process and to improve th quality of products, it is very important to choose and optimal assembly sequence. In this paper, we propose a methodology that generates an optimal assembly sequence by using various methods and the knowledge of experts. To illustrate the effectiveness of the proposed methodology, a knowledge-based system is developed, The built system is applied to the case of UBR(Unit Bath Room). The applying result showed the applicability of the developed system.

In order to do a maintenance task, a maintenance operator should learn the basic skills of the maintenance task such as assembly and disassembly (A/D). However, the key of the learning process is to learn the A/D task intuitively and naturally. Haptic guidance promises to give effectiveness and benefit qualitatively since a person can be trained to do the optimal task based on information that comes from an expert, database, or intelligent algorithms. By applying haptic guidance, a maintenance training process can be made more intuitive and natural in a virtual environment. This paper describes the development of a maintenance training system by using haptic guidance.

In this study, it is performed that the assessment of feasibility of developed material processing facilities using tele-operation manipulator system for the pyroprocessing. To evaluate the performance of developed facilities using tele-operation system, several performance indices are considered as remote visibility, remote reachability and remote manipulability. These are applied to RHEM (Remote Handling Evaluation Mock-up) and digital mock-up system respectively. Through this approaches, several requirements for the system improvement are deduced and preliminary inspection for real system application is fully performed. Additionally, assembly and disassembly tasks for the repair of remote handling system are also examined remotely in RHEM and evaluated those performances.

Remanufacturing of automobile parts is important for increasing the recycling resources. ECU(Electronic Control Unit) systems are becoming an increasingly important part of an automobile. But production company are reported in the ECU remanufacturing industry of domestic automobile parts due to a lack of remanufacturing technology and marketability. This paper introduces the ECU of remanufacturing, also grasps the structure and the analyzes failure cause that is external factors and fault in the characteristic design and steps in the Independent ECU remanufacturing process. The ECU manufacturing industry of the US was examined. The results in this paper could be used as the system information for further remanufacturing industry of domestic automobile parts.

In or automotive engineering education is introduced. Main objective of the system is teaching disassemble/assemble procedure of automatic transmission of a vehicle to students, who study automotive engineering. System includes vehicle transmission, set of tools and mechanical facilities, two video cameras, computer with developed software, HMD glasses and two LCD screens. Developed software gives instructions on assembling and disassembling processes of real vehicle transmission with the help of augmenting virtual reality objects on the video stream. Overlaying of 3D instructions on the technological workspace can be used as an interactive educational material. In disassembling process, mechanical parts which should be disassembled are augmented on video stream from video cameras. Same is done for assembling process. Animation and other visual effects are applied for better indication of the current assembling/disassembling instruction. During learning and training, student can see what parts of vehicle transmission and in which order should be assembled or disassembled. Required tools and technological operations are displayed to a student with the help of augmented reality, as well. As a result, the system guides a student step-by-step through an assembly/disassembly sequence. During educational process a student has an opportunity to return back to any previous instruction if it is necessary. Developed augmented reality system makes educational process more interesting and intuitive. Using of augmented reality system for engineering education in automotive technology makes learning process easier and financially more effective.

As production, distribution, consumption and processing increase with the development of industrial societies, the importance of resource depletion and environmental problems is increasing day by day. This has led to increased research and interest in remanufacturing that can satisfy both environmental and economic aspects. Currently, the remanufacturing industry is progressed in Korea with automobile parts with as the central figure, and it needs to be expanded into various areas. In this study, the failure type analysis and FMEA were performed on the hydraulic pumps used in construction and industrial sites for the development of the standard remanufacturing process plan, and the actual disassembly and reassembly process was carried out. Remanufacturing products were manufactured through the analysis contents and drawing process, performance tests were conducted in accordance with RS B1501 criteria to evaluate performance, and all of these products passed the test criteria.
