Combining digital automation solutions throughout recent manufacturing process is essential. Advanced robot and mechanical techniques are required for design, manufacture, and distribution process. Manual design of repetitive similar mechanical components during the development phase of these advanced machines and robots can occur wasting time and money. Developed gear design module, which is the power transfer system mechanical component, was programmed in the Visual Basic language in CATIA V5 environment. Automation Process is Based on Parametric Modeling Method. and it was found to be effective in reducing design time compared to designers manual modeling.

Recently, the use of tubes in the manufacturing of the automobile parts has increased and therefore many automotive manufactures have tried to use hydro-forming technology. The hydro-forming technology may cause many advantages to automotive applications in terms of better structural integrity of the parts, lower cost from fewer part count, material saving, weight reduction, lower spring-back, improved strength and durability and design flexibility. In this study, the whole process of sub-frame parts development by tube hydro-forming using steel material is presented. At the part design stage, it requires feasibility study and process design aided by CAE (computer aided design) to confirm hydro-formability in details. Overall possibility of hydro-formable sub-frame parts could be examined by cross sectional analyses. All the components of prototyping tools are designed and interference with press is examined from the point of geometry and thinning.

This paper presents an app lication of heuristic approach to problem of designing reliable network expansion. The problem essentially consists in finding the network topology that satisfies given set of reliability constraints. To efficiently solve the pr

이상과 같은 제어계의 구성방법으로 제어계를 설계할 경우에는 오차신호에 대한 PI제어기와 플란트의 상태피이드백을 아울러 행하는 제어계로 됨을 알 수 있으며, 또한 응답 시뮬레이션 결과로부터 알 수 있듯이 본 연구에서 제안하는 방법으로 제어기를 구성할 경우 양호한 제어가 가능하다. Fig.3의 플로우챠트의 그림에서 점선으로 표시된 실시간제어실험의 프로그램은 구성은 되어 있으나 실제로 실험을 행하지 못한 아쉬움이 있으며, 다음 기회에 이 부분의 실험도 행하고자 한다.
