This study analyzes trends and characteristics of the machine tool remanufacturing industry and proposes a standard process that considers environmental impact assessment during the remanufacturing process. First, trends in remanufacturing and environmental regulations are reviewed. And the current status of the machine tool remanufacturing industry and cases of national R&D projects related to machine tools are analyzed. Machine tool remanufacturing has a high resource saving effect, and remanufacturing is carried out as a finished product rather than as a part. And the scope of remanufacturing work is very wide due to the performance improvement of the machine and the addition of features. In order for the machine tool remanufacturing industry to be competitive, it is necessary to create products with high added value. In addition, in order to respond to international environmental regulations, it is necessary to secure related data by conducting an environmental impact assessment together during remanufacturing.

Remanufacturing is an industrial manufacturing process. The merits of remanufacturing are to reuse old products to perform like a new product and to save energy, natural resources, landfill space and to reduce air pollution by less re-smelting. This paper proposes a systemic approach for activating the domestic remanufacturing industry. The approach is based on inside and outside regulations to apply remanufacturing companies. And, we analyzed the state and problems of remanufacturing industry for automobile parts.

재제조는 사용 후 제품을 일련의 과정을 거쳐 신품의 성능수준으로 복원하는 방법으로 물질 재활용에 비하여 자원에너지 절감효과가 높고 환경부하가 작아 경제성과 환경성을 동시에 만족하는 고부가가치 자원순환방법이다. 재제조를 통한 자원순환은 최근 이슈가 되고 있는 자원수급 불균형 및 일자리 부족 등의 문제 해결에도 크게 기여할 수 있다. 이에 본 연구에서는 재제조의 특성 및 효과를 고찰하고, 우리나라와 미국, 유럽, 일본, 중국 등 해외 주요국의 재제조산업 현황, 기술수준, 제도 등을 비교, 분석하여 문제점을 도출하였으며, 이를 바탕으로 국내 재제조산업 활성화를 위한 발전 과제를 제시하였다.

Remanufacturing is one of the most important resource recycling technology in response to resource depletion and environmental pollution. Domestic remanufacturing industry don't invigorate compared to other advanced countries because of low price and reliability of remanufactured product. In this study, remanufactured hydraulic pump and solenoid valve were evaluated durability by accelerated life test. In order that standard remanufacturing process was developed by core analysis and failure mode and effect analysis. And cores were remanufactured by standard remanufacturing process. For accelerated life test, the evaluation item and criteria were deduced by results of FMEA, reliability standards and enterprise interior criteria. To evaluate durability of remanufactured product, the remanufactured hydraulic pump and solenoid valve were evaluated performance after accelerated life test and the results were satisfied with criteria. This study showed that remanufactured products have a similar level of durability to new products by definition of remanufacturing.

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.

국내 알루미늄 산업에서 압출공정은 생산량 기준 40% 이상의 비중을 차지하고 있는 주요 공정이다. 국내 알루미늄 압출업체 대부분이 30년 이상 된 노후 설비를 이용하여 생산하고 있기 때문에 제품 정밀도 및 품질 저하, 낮은 생산성 등의 문제를 격고 있다. 압출 설비는 한번 도입하면 주요 부품의 마모 또는 파손 발생 전에는 설비를 교체하지 않는 구조로 신규 설비에 비해 생산성 감소 및 불량률이 증가하기 때문에 설비의 유지 관리가 중요하다. 노후 압출기는 부품의 도면이 소실된 경우가 많아 현장에서 적절한 보수가 어렵고 유지 관리를 위한 기술력 부재로 인해 재제조에 어려움을 겪고 있기 때문에 해체 단계에서부터 체계적인 재제조 방안이 고안되어야 한다. 본 연구에서는 노후 압출설비의 재제조를 위해 재제조 고장모드 영향분석 방법을 고안하였다. 부품에 대한 재제조 대상 부품의 파손에 대한 심각도, 압출 공정 중 고장/파손에 따른 수명 그리고 재제조에 따른 자원순환의 가치를 고려하여 위험우선순위를 산정하고 재제조 대상을 선정하였다. 노후 압출기의 재제조 공정의 표준화 정립을 위해 노후 압출기의 구조에 따른 모듈 및 부품에 대한 분석 등을 통해 재제조 고장모드 영향분석을 수행하였으며 부품별 우선순위를 선정하여 자원순환의 효율성 및 제품 품질 안정화를 위한 재제조 연구를 수행하였다.

현재 우리나라의 차량 증가에 따른 폐차도 증가추세에 있어 이에 따른 각종 환경오염 문제로 인해 자원 재순환에 대한 관심이 고조되고 있는 실정이다. 본 연구에서는 국내 자동차 부품 재제조시장의 사업도입에 따른 경제적 효과를 정량적으로 평가하고자 자동차의 부품중 상대적으로 재제조율이 낮은 부품인 범퍼, 도어, 펜더에 대해서 비용편익을 분석하였다. 분석 결과 각각 비용 편익은 제품별 개당 54,000원으로 발생하는 것으로 나타났고, 신제품의 50%를 재제조할 경우 매립비용의 절감으로 개당 226,060원의 이익이 발생하는 것으로 나타났다. 이와 같이 범퍼, 도어, 펜더를 재제조 했을 경우 상당한 편익이 발생하여 재제조업체의 충분한 경제성 확보가 가능할 것으로 판단된다.

The domestic remanufacturing industry is concentrated in auto parts, so it is necessary to expand into various industries. In the domestic aluminum industry, the extrusion process accounts for more than 40% of the total, but the old and management of the extrusion equipment is not done properly. In particular, the extruder has a structure in which equipment is not replaced until major parts are damaged or worn, so there are problems such as lower process precision, productivity and production efficiency compared to new equipment, and high maintenance costs. In this study, the old extruder was remanufactured for major high-risk parts through Failure Mode and Effect Analysis(FMEA), and the process level and performance of the extruder were evaluated before and after remanufacturing. Compared to the existing extruder, the standard deviation of the remanufacture extruder was reduced by 93.5%, 57.9%, and 70.0%, respectively, in major process control items such as container temperature, billet temperature, and ram speed, keeping performance constant. In addition, it was possible to produce products with complex shapes that could not be produced before due to problems such as dimensional deviation within tolerances. In this study, remanufacturing guidelines were presented by analyzing the effect of failure modes of the old extruder, and the performance improvement of the extruder was confirmed.

The need for remanufacturing ships and various mechanical components continues to increase along with environmental problems. Research on remanufacturing is being carried out in various fields, but research on cleaning is quite insufficient. In particular, there is no research on the cleaning-ability of diverse mechanical components. In order to increase the life cycle of mechanical components, remanufacturing must be considered from the step of design. Particularly, it is also very important to evaluate the degree of easiness in cleaning to remove various pollutants generated by long-term use quickly as well as easily. In this study, the degree of easiness in cleaning is defined as cleaning-ability. In fact, remanufacturing components can be easily done only when cleaning-ability is set high from the step of design. The purpose of this study is to evaluate the cleaning-ability of ships and various mechanical components. The details of easiness in cleaning are cleaning and drying identification, accessibility to cleaning tools, convenience in cleaning, and convenience in drying. This study presents a quantitative procedure to evaluate cleaning-ability, derived various factors influencing each of the details of easiness and their ranges, and gave scores to the factors according to their ranges. The weight was also calculated for the details of easiness in cleaning and the factors. Lastly, this researcher suggests a scoring procedure to evaluate cleaning-ability quantitatively and the total weight of cleaning-ability.
