Over the past decade, changes in product development processes and increased consumer demands have dramatically influenced engineering working practices and targets. The information technology revolution has made its appearance concurrent to this relentless escalation in product engineering requirement. It has offered hopes for improved productivity despite these increasing demands. The wide availability of personal computing power, virtually inexhaustible sources of information and an abundance of computerized engineering tools have created great expectations. Knowledge information modeling system and database were developed using ASP and Microsoft SQL 2000 Server to share the DB that can be utilized to process on the web.

Intelligent Robot is considered as one of the Next Generation Growth Engine in many countries. The application fields are expected to be widen from 80's robotics for manufacturing to many applications such as military, space, medical, personal, etc. To reduce the R&D investment risk Technical Roadmap is prepared by Japan, Europe and Korea. In this paper, the technical Roadmap of the countries was analysed to get the idea of future of Robotics. Robotics is considered as one of solutions of future aged society. Robot can assist and company with elderly people in the near future. On the other hand, Robot is considered as a core technology of manufacturing competitive power. Industrial competitiveness also would be dependent on robot technology. Special Service robot has many application areas and each country has different target based on the situation. With the comparison of technical roadmap, we have suggested some ideas to improve Korea's roadmap.

In this paper, an integration tool for the factory automation communication is proposed. It can apply to three kinds of Fieldbus, Manufacturing Message Specification and Personal Digital Assistance based systems in the factory environment. This paper focuses on the development of the testing tool and object-oriented design concepts for the synthesis of communication modules from the factory level to the field level. The integration of each communication module in the distributed environment gains importance for the realization of heterogeneous information processing systems.

We developed the advanced LTPS (A-LTPS) manufacturing process. The a-Si TFT process was combined with selectively enlarging laser crystallization (SELAX) technology to improve the carrier mobility in the region where the peripheral circuits are to be fabricated. A 2.4-inch IPS-pro LCD panel for personal digital assistant use was successfully fabricated using the developed technology.

A CAM program for forming design Automated of CAM for Spring using car was developed in this study. This program was written in AUTO LISP on the AUTO CAD system with a personal. An approach to the system is based on the kinemateic of the object function. We make a determination of an cam programming. A CAM spline is continuous in displacement. velocity and acceleration. This program which can design Coil Spring shapes will successfully support CAN designing and manufacturing for Small & Medium companies.

In this paper, an off-line programming(OLP) system is presented as the three dimensional graphic simulator and one of the human-robot interface systems for industrial robots. The OLP system has been especially developed to testify robot programs visually using three dimensional geometric modeling and graphics technologies in personal computes. A special feature is its capability of collision detection and of comparing performance of control algorithms. This paper places the focus on the structure and major characteristic of OLP system.

In this paper, a 3-D computer-aided die design process was developed for automobile rear frame with drawing, trimming, flanging, cam-piercing and piercing for tool design. The tool design has been done using Pro/Engineer on a personal computer. It is composed of four stations. The goal of this research is to apply each of stations for the standard tool specification to each station.

This paper embodies the agent based cinder monitoring system which supports PDA{Personal Digital Assistant). Monitoring system automatically manages data by using data managing agents such as a state managing agent, a location managing agent, a badness managing agent, a circumstances managing agent, etc, and uses a massive data processing agent to manage massive data. The development of agent based data monitoring system for the stable cinder reuse will be an epoch-making method to develop the process mechanized or manual-labored that widely spreads into the real-time automated process.

In seeking further efficiency in production preparation, it is common to examine assembly sequences using digital manufacturing. The assembly sequences affect the product evaluation, so it is necessary to test several assembly sequences before actual production. However, because selection and testing of assembly sequences depends on the operator's personal experience and intuition, only a small number of assembly sequences are actually tested. Nevertheless, there is a systematic method for generating assembly sequences using a contact-related figure. However, the larger the number of parts, the larger the number of assembly sequences geometric becomes. The purpose of this study is to establish a systematic method of generating efficient assembly sequences regardless of the number of parts. To generate such assembly sequences selectively, a "Tournament Tree," which shows the structure of an assembly sequence, is formulated. Applying the method to assembly sequences of a water valve, good assembly sequences with the same structure as the Tournament Tree are identified. The structure of such a Tournament Tree tends to have fewer steps than the others. As a test, the structure is then applied for a drum cartridge with 38 parts. In all the assembly sequences generated from the contact-related figures, the best assembly sequence is generated by using the Tournament Tree.
