Recently much attention in building smart factory has been dramatically increased. Despite the growing interest in smart factory, few practical guidelines exist how to successfully build smart factory. The purpose of this study is to postulate and develop a road map for building successful smart factory. To enhance mundane realism, we design the road map through University-Industry research collaboration. Specifically, drawing analysis of University-Industry research collaboration, we design a prototype and detailed road map or building successful smart factory. Moreover, we apply the road map into actual smart factory development. By doing so, we successfully prove the effectiveness of the road map. Therefore, this study provides the valuable guidelines and directions to build a successful smart factory. Ultimately this study is able to help a variety of factories which establish and implement smart factory. Further, we hope that this study will be placed to be an important foundation research on behalf of smart factory building.

Industrial robotic arms are widely adopted in numerous industries for manufacturing automation under factory settings, which eliminates the limitations of manual labor and provides significant productivity and quality benefits. The U.S. modular construction industry, despite having similar controlled factory environments, still heavily relies on manual labor. Thus, this study investigates the U.S., Canada, and Europe-based leading modular construction companies and research labs implementing industrial robotic arms for manufacturing automation. The investigation mainly considered the current research scope, industry state, and constraints, as well as identifying the types and specifications of the robotic arms in use. First, the study investigated well-recognized modular building associations, the Modular Building Institute (MBI), and renowned architecture design magazine, Dezeen to gather industry updates. The authors discovered one university lab and a few companies that adopted Switzerland-based robotic arms, ABB. Researching ABB robotics led to the discovery of ABB's competitor, Germany-based KUKA robotic arms. Consequently, research extended to the companies and labs adopting KUKA models. In total, this study has identified seven modular companies and four research labs. All companies employed robotic arms and gantry robot combinations in a production-line-like system for partial automation, and some adopted design standardization for optimization. The common goal among the labs was to achieve greater flexibility and full automation with robotic arms. This study will help companies better implement robotic arm automation by providing recommendations from investigating its current industry status.

스마트팩토리는 제조생산 전 과정이 디지털 자동화 솔루션으로 결합돼 생산성 및 품질, 그리고 고객만족도를 향상시키는 지능형 공장으로 스스로 제어할 수 있는 공장을 말한다. 독일, 유럽, 미국 등을 중심으로 전세계 제조 산업에서 급속도로 변화하고 있다. 우리 정부도 이러한 변화에 대응하기 위해 중소중견기업을 위한 스마트팩토리 보급확산 정책을 펼치고 있으며 산업자원통상부, 중소벤처기업부, 중소기업기술정보진흥원, 각 지역 테크노파크 등 관계부처 및 기관들과 삼성, SK, LG 등 대기업들이 스마트팩토리 지원 사업에 적극적인 투자를 하며 제조 스마트화에 나서고 있다[1]. 공장자동화(Factory Automation, FA) 구축에는 이기종 장비의 연결에 대해 많은 이슈들이 있다. 다양한 장비로부터의 다양한 통신 구성이 가장 힘든 측면이 그 이유이다. 같은 회사 제품들로만 구성되거나 표준안이 존재하면 모르겠지만, 오래된 장비와 최신의 장비, 사용 환경도 제각각인 장비들이 일련의 통신을 통해 통합 구축을 하려니 구축하기가 쉽지 않다. 이런 문제점을 해결하기위한 방법으로 전 세계적으로 널리 보급되어 있는 자동화 프로토콜의 하나이고, 대표적인 설비 제어시스템인 PLC의 수많은 공업 기기에서 통신표준으로 사용하고 있는 FieldBus중 하나인 Modbus를 이용하여 통신 하는 방안을 제시하고자 한다.

This paper describes an experimental embedded tiny web server system that monitors the processing of manufacture using the Internet. The object of this study is developing of an embedded tiny web server that connects the stand-alone machines in factory to the Internet. Using the World Wide Web (WWW), we proffer user-friendly environments to users. Anyone with a web browser may easily access the processing of manufacture in the factory. Through connecting different network system, our web server extends the private networks to the Internet, the global networks. Our embedded tiny web server is ideal for process control, building and facility management system, factory automation and even home automation.

Ultrasound waves interact strongly with the orientation and sequence of the plies in a layup when propagating in the thickness direction of composite laminates. Also the layup orientation greatly influences its properties in a composite laminate. If the layup orientation of a ply is misaligned, it could result in the part being rejected and discarded. Now, most researchers cut a small coupon from the waste edge and use a microscope to optically verify the ply sequences on important parts. This may add a substantial cost to the production since the test is both labor intensive and performed after the part is cured. A nondestructive technique would be very beneficial, which could be used to test the part after curing and requires less time than the optical test. Therefore we have developed, reduced, and implemented a novel ply-by-ply vector decomposition model for composite laminates fabricated from unidirectional plies. This model decomposes the transmission of a linearly polarized ultrasound wave into orthogonal components through each ply of a laminate. High probability is found, by comparisons between the model and tests, in characterizing cured layups of the laminates by using the proposed method.
