This paper presents an embodiment of design integration framework corresponding to changes in the latest manufacturing environment. The embodied system is named by 'WEB-KBE System' because it supports a product design with a KBE technique based on web environment. The final purpose of the work is to implement a web-based integration design environment with a KBE technique to support non-skillful designers. The framework of the system Is designed to support necessary items in user-centric design environment. Two case studies were applied to the WEB-KBE system to evaluate the efficiency, flexibility, extensibility, and reusability of the system. The examples are [1] CART integration design environment construction and (2) Exhaust Duct Saddle Support integration design environment construction. In the former case, it took a period of 8 months for modeling and implementation of the WEB-KBE prototype system. However, with the high extensibility and reusability of WEB-KBE system, the second case required only a period of one month for modeling and implementation of the system. We conclude that the presented WEB-KBE system can bring fair effects on implementing a knowledge based design environment in aspect of time and expense.

In order to enhance the productivity of design and manufacture of injection molds, various computer-aided systems have been developed and introduced to mold manufacturers. The customized 3-D CAD systems for mold design is one of the most representative computer-aided system. However, these systems usually do not provide a convenient way to access and manage design knowledge implemented in them. To overcome this shortage, knowedge-based engineering systems have been developed, and now they are imbedded as modules of commercial CAD systems. In this paper, we introduced a 3-D design system for standard mold base based on Knowledge Fusion, a commercialized KBE system imbedded in Unigraphics. By introducing KBE system, design knowledge can be exposed to the users and modified by the end-users.

오늘날의 세계 시장에서는 그 경쟁이 점점 복잡해지고 있다. 이 경쟁에서의 승리는 적절한 시 기에 적절한 새모델을 제시하느냐에 달려 있다. 불행히도 제품설계 및 제조사이클에는 종종 많은 시간이 요구되는 루프가 포함되어 있다. 즉 설계변경과 재작업 사이클 때문에 시자출하 시간이 지연된다. 이러한 변화를 동적으로 취급하고 적절한 시점에 적절히 이동할 수 있는 전략을 개 발하는 것이 오늘날 세계경쟁에서의 성공에 필수적이다. 이러한 문제점들의 해결방안으로 동시 공학, 혹은 지식베이스 시스템을 포함하는 지식베이스 엔지니어링(KBE:knowledge-based engineering)이 소개되는데 이러한 지식베이스엔지니어링은 기존의 제품개발 방법론을 개선하기 위한 지능적인 설계도구로서 컴퓨터를 사용하는 새롭고 흥미로운 가능성을 제시한다. 이러한 설계도구는 조직적이고 체계적으로 지식을 수집하여 활용함으로써 동시공한(concurrent engineering)방법론을 효율적으로 수행하는 데에 매우 유용하다.

Very special and tentative considerations including emotional aspects are required to apply any new mechanism and methodologies for manufacturing fields due to several reasons. This study reviews the characteristics of manufacturing collaborations through specific cases applied digital engineering to enhance the collaboration performance in manufacturing domains. Two cases of collaboration related with automotive manufacturing process are analyzed to extract meaningful insights for better collaboration model suggestions. The first case deals the robot simulation to find out advance errors in jig and fixture design during the various welding process of body-in-whites. The effective communication protocol to share their idea and agreed schedules are essential for this collaboration. More severe requirement of collaboration between R&D and manufacturing departments are studied in the second case for e-coating process. The invisible barriers among different departments are lowered by the process application of Computer Aided Engineering which can make sure their own interesting effectively. Those technical and managerial suggestions can be used when the information system and standard process are sought to implement and update not only when innovation projects are executed.
