오늘날 제조업에 있어서는 시장의 다양화, 원가절감 및 리드타임의 단축이라는 대내외적 요구에 부응할 수 있는 기술 생산체재의 확립이 요구되고 있다. 이에 따라 설계 및 기술변경(Engineering Change)에따른 원가상승을 막기 위해 CAE(Computer aided engineering), CAD(Computer aided design)의 도입을 서두르게 되었고 CAD데이타의 효율적 이용에 의한 가공 및 생산적 측면에서 CAM(Computer aided manufacturing)의 도입도 검토하게 되었다. 본 논문은 이러한 개념의 발상동기와 이를 뒷받침하기 위한 한국 아이 비 엠이서 제공하는 하드웨어 및 소프트웨어를 소개하고 공장자동화를 위한 기술 생산 통합시스템의 구축이라는 측면에서 아이 비 엠이 추구하는 방향을 검토하고 있다.

The substructure of Light Rail Transit is mainly built on elevated structure that is composed of pier, girder and bridge deck. The bridge deck mostly has been made by field formed reinforced concrete so far. The objectives of the study are to find a method for design and construction of the new bridge deck. I-beam is fabricated to make grid and concrete is poured on it at factory. This type can be used for maintenance of duty line by advantages such as good quality control and short construction time.

For solving problems of manpower and improving working environment, Robot System have been introduced. In the past, Robot System was adopted mass production, indoor factory condition, but present Robot System is applied to many other fields. This applied field is Robot System was adopted fruit harvest, maintenance, and so on. The developed Multi-Linked Lifter is applied to eminant multi-purpose working. The purpose of this study is to develop control algorithm for this equipment composed of multi-linked manipulator.

To survive in the intensive world wide automotive market, more and more automotive companies are investing their resources into concurrent engineering systems (CE) based on the combined CAD/CAM/CAE/ PDM technology. The main objectives of CE in automotive companies are the quality improvement of products and the reduction of cost and time to market. Remarkable effects are appearing from some of these companies. As shown in this paper, these successful automotive companies have been focusing on establishing the new process and methodology in applying CE into their car development process.

In this paper, the voltage-fed series compensated inductor type load-resonant high-frequency inverter is originally presented for driving a newly-developed silent discharge ozone generating tube. The effective power regulation scheme of this ozonizer is proposed, which is based on PDM (Pulse Density Modulation) related PWM strategy due to DSP implementation. The effectiveness of this inverter type ozonizer is proved in simulation and experiment.

Industrial safety is one of the crucial agenda for Government as well as Manufacturing Industry. To cope with the needs, a great deal of policies and technical implementation have been proposed and implemented. With a great increasing attention on the Industry 4.0 and Smart Factory, industrial safety has received as a crucial agenda by the manufacturing industry in particular. Up until now, almost all of them have been made from the environmental aspects, rather than operator or workers. In this paper, we present our research results how to increase the workers' safety via smart factory technology, such as IoT and CPS. Our approach has been to see the problem from SE perspectives, to draw the real issues from the various stakeholders, and define how to solve the problem based on the emerging technologies. The developed systems can give conceptual framework for the 'smart' industrial safety system by providing solution architecture for how to monitor the location of workers, and moving equipments, and generate solutions how to avoid safety problems between them if detected.
