After the US government declared 3D printing technology a next-generation manufacturing technology, there have been many practical studies conducted to expand 3D printing technology to manufacturing technologies, called AMERICA MAKES. In particular, the Keck Center, located at the University of Texas at El Paso, has studied techniques for easily combing the 3D stacking process with space mobility and expanded these techniques to simultaneous staking techniques for multiple materials. Additionally, it developed convergence manufacturing techniques, such as direct inking techniques, in order to produce a module structure that combines electronic circuits and components, such as CUBESET. However, in these studies, it is impossible to develop a unified system using traditional independent through simple sequencing connections. This is because there are many problems in the integration between the stacking modeling of 3D printers and post-machining, such as thermal deformations, the precision accuracy of 3D printers, and independently driven coordinate problems among process systems. Therefore, in this paper, the integration method is suggested, which combines these 3D printers and subsequent machining process systems through an Internet-based cloud. Additionally, the sequential integrated system of a 3D printer, an NC milling machine, machine vision, and direct inking are realized.

Many data mining techniques have been proved useful in revealing important patterns from large data sets. Especially, data mining techniques play an important role in a customer data analysis in a financial industry and an electronic commerce. Also, there are many data mining related research papers in a semiconductor industry and an automotive industry. In addition, data mining techniques are applied to the bioinformatics area. To satisfy customers' various requirements, each industry should develop new processes with more accurate production criteria. Also, they spend more money to guarantee their products' quality. In this manner, we apply data mining techniques to the production-related data such as a test data, a field claim data, and POP (point of production) data in the automotive parts industry. Data collection and transformation techniques should be applied to enhance the analysis results. Also, we classify various types of manufacturing processes and proposed an analysis scheme according to the type of manufacturing process. As a result, we could find inter- or intra-process relationships and critical features to monitor the current status of the each process. Finally, it helps an industry to raise their profit and reduce their failure cost.

This case study covers the Knowledge Management research paper that explores the clear idea about the knowledge practicesthat are used in the corporate sector to achieve the strategic advantage over the competitors. The quoted example of the three manufacturing firms TATA MOTORS, BHEL, and M&M have tried to compare the Knowledge practices in these firms, which explores the concept clearer that the competitors can use the same or the different type of knowledge practices to achieve the competitor advantages. In order to help knowledge management goals, an integrated knowledge management system consisting of the knowledge management techniques and technologies are used. The knowledge Management is supported by different techniques and practices whichare knowledge content, people skills, technology and strategy based. The technology and techniques supports these factors of knowledge management. The paper discuss different techniques and processes adapted by three Indian organizations and a comparison is made to suggest the guidelines of KM practices to manufacturing Industries.

Technical advances in manufacturing techniques and applied technologies have been made for bi cell manufacture, and are currently being implemented in the areas of discrete electrode / bi cell assembly, and electrode / separator lamination. Not only have improvements been noted in the reliability of the mechanical assembly and the increase in yields and decrease in costs, battery electrical performance has also been enhanced thru these assembly techniques. Evidence has been shown that the lamination techniques can influence porosity and electrolyte dispersion, and therefore electrical performance and long term reliability of the cells.

The objective of this research is to select the most effective technique from AMT (Advanced Manufacturing Technologies) and IMP (Innovative Management Practices) for improving manufacturing performance in shipbuilding enterprises. The research consists of several principal steps. The first step is to design critical criteria in evaluating manufacturing performance in shipbuilding enterprises. The second step is to develop sub-criteria of the critical criteria. The third step is to develop a four level AHP (Analytic Hierarchy Process) structure using the critical criteria, sub-criteria and techniques from AMT and IMP. The fourth step is to develope the pairwise comparison matrix by each level of AHP structure, which was based on survey data collected at the H heavy industry. And the last step is to select the most effective technique from AMT and IMP by using AHP analysis. The results of AHP analysis did not show clear difference in priority between techniques of AMT and IMP in terms of manufacturing performance of the shipbuilding enterprise. Thus, each critical criterion was assigned modified weights and examined the priority change of techniques by conducting performance sensitivity analysis.

현대 주조산업에서는 적층제조기술과 같은 신기술을 도입하면서 과거에는 불가능했던 일들의 실현가능성을 보여주고 있다. 이미 해외에서는 적층제조기술을 활용한 중자 생산 및 적용 사례가 심심치 않게 보도되고 있으며, 정부지원 하에 고유 기술들을 개발하고 시장을 확장해 나가고 있다. 반면 국내에서는 고유장비 기술은커녕 적층제조기술의 활용조차 전무한 실정이다. 이러한 상황에서 적층제조기술의 도입과 국산화는 반드시 필요하다. 본 논문의 각 장에서는 여러가지 적층제조기술 중 접착제 분사 기술에 관련된 적층제조장비의 개발 과정에서부터 개발 장비를 활용한 산업용 중자 생산의 내용을 다루고 있으며, 실제 주조 산업의 적용 가능성에 대해서 언급하고 있다.

The global aircraft-manufacturing industry ecosystem is characterized by the international division of labor through the worldwide supply chain and by the concentration of value added at the top of the supply chain. As a result, the competition for entry into the top supply chain and for order expansion is becoming increasingly intensive. To increase their orders, domestic aircraft manufacturing enterprises need to enhance their competitiveness by evaluating and analyzing it. However, most domestic aircraft manufacturing companies are unaware of the need to quantitatively evaluate their competitiveness. It is challenging to perform such an evaluation, and there are few research cases. In this study, we quantitatively evaluated and analyzed the competitiveness of domestic aircraft manufacturers by using data mining techniques. Thereby, implications for enhancing their competitiveness could be identified.

Management is under constant pressures to achieve competitiveness in production in most manufacturing companies. The adoption of management techniques(MT) such as TQM, MRP, ERP and so on has been a logical response for better performance to many companies. Besides, these companies commonly adopt a number of such techniques with high expectation for performance improvement. However, expected improvement in performance is not guaranteed unless necessary ingredients exist for those techniques. Many research studies have focused on the nature of successful adoption of management techniques in the past. However, most studies have been related to a single technique and its effects. When more than one techniques are in use in a company, focusing on a single technique limits the value of analysis. This paper focuses the value of MTs adopted in a company in multiplicity and compares the relative characteristics of MTs one another. Especially, the purpose of this paper is to examine the comparative nature of MTs adopted In manufacturing companies and the elements of MT success in relationship with information systems and organizational adjustment for adoption of MTs. The result of the analysis shows that the more efforts are exhorted for the adjustment of information systems and organizational structures to accommodate the MTs, the more success from the adopted techniques results. However, the extent of adjustment for different management techniques differs one another due to the nature of each technique. With regard to the comparative impact of adjustment of information systems and that of organizational structures, the result shows that the latter has more direct and greater impact than the former.

본 연구에서는 경주 금관총에서 출토된 비단벌레장식 마구류의 제작 기법에 대해 비단벌레 날개를 중심으로 조사하였다. 비단벌레 날개는 상단 골격부를 제거한 후 금동투조판 아래에 놓여 장식으로 사용되었으며, 부착성 증대를 위한 가공 흔적 등은 확인되지 않는다. 금관총에서 출토된 비단벌레장식 마구류는 안교, 등자, 행엽, 죽제장니가 있으나 등자를 제외한 마구류는 대부분 파손·유실되어 전체적인 제작방법을 확인하는데 어려움이 있었다. 비단벌레 날개의 고정 방법은 바탕재에 따라 달라지며, 목심을 바탕재로 사용하는 등자와 안교는 소형정을 사용하고 죽제장니나 철제를 바탕재로 사용하는 유물은 옻칠을 사용하여 고정 후 금동투조판으로 압착하여 결합한 것으로 확인된다.
