  • Engineering database for CIM of injection mold production has been developed to manage design information and parameters of injection mold. The database has direct connection with product data management system and management database. Design specifications are generated in initial stage of mold design with integration of management information. Design parameters and bill of materials for mold base parts are generated during the CAD process and transferred to the manufacturing database and procurement system. Standard modules for parts and mold base are constructed using national standard and legacy data of industries. The engineering database provides important information route for CIM of injection mold design and production.

  • Nowadays, there are many efforts to integrate CAD/CAM and other systems. The key of integration is engineering database implementation through the product data definition. In this paper, we suggest the product data definition and their properties for electronic consumer product throughout the requirement analysis for engineering database. Electronic consumer products include electric/electronic parts. as well as mechanical part which mainly compose of machinery. The paper is composed of three parts: the first is analysis about engineering data base. the second is understanding of product data structure and properties. and the last is modeling of product data including static and dynamic characteristics.

  • 지금까지 재 제조에 필요한 자동차 중고부품은 주로 정비업체에서 회수하여 사용하였으나, 회수체계가 정비되어 있지 않아 자동차 중고부품 수집에 많은 시간과 경비가 소요되었으며, 폐차업체에서 생산되는 많은 자동차 중고부품은 재 제조에 활용되지 못하고 있는 실정이다. 본 시스템은 폐차장, 정비업체 등에서 자동차 중고부품 정보를 입력하고, 재 제조업체에서는 이들 정보를 이용하여 재 제조에 필요한 자동차 중고부품을 회수할 수 있게 함으로써 자동차 중고부품 회수체계를 확립하고 자동차 중고부품의 안정적 수급 방안을 마련할 수 있도록 설계하였다. 본 시스템은 자동차 부품 재 제조에 필요한 자동차 중고부품을 수집 관리하기 위한 물류정보시스템으로 DISRMPA(Distribution Information System for Recovery and Management of used Parts of an Automobile)라고 부른다.

  • We suggest a 3D vision inspection algorithm which is based on the external shape feature. Because many electronic parts have the regular shape, if we have the database of pattern and can recognize the object using the database of the object s pattern, we can inspect many types of electronic parts. Our proposed algorithm uses the geometrical pattern matching method and 3D database on the electronic parts. We applied our suggested algorithm fer inspecting several objects including typical IC and capacitor. Through the experiments, we could find that our suggested algorithm is more effective and more robust to the inspection environment(rotation angle, light source, etc.) than conventional 2D inspection methods. We also compared our suggested algorithm with the feature space trajectory method.

  • This study aimed at developing the standard questionnaire database system for rural development. By the previous study for the hierarchical listing of the factors related to rural development in the village level, the targetting questionnaire items pool was proposed. The data base system basically consisted of 3 parts: general, principal and sectoral parts for rural development. General and principal parts had the detailed questionnaires without any further hierarchy, but sectoral one 4-step hierarchy from high/medium/low levels to detailed questionnaires. Tentatively, total 417 questionnaires statements were written with 5 questioning styles: single choosing, multiple choosing, tabular, writing and special questions. Through the checking done by college students team from rural area, the database system having 467 questioning statements was finally developed.

  • Outfitting systems in marine vessels have many kinds of standard parts. Ship CAD system should support the designers with an efficient tool for the modeling of outfitting parts such as pipes and valves. We develop a practical procedure for a part master model that combines ship CAD systems with the industrial standard. Part master or catalogue database of standard equipments is included in the database of ship CAD. The part master makes the associations of three dimensional modeling with the industrial standard. Moreover, it reflects the automatic modeling to maintain attributes that are disclosed in the entity of each part master in order to reduce the modeling time. Entity and attributes of pipe and valves are chosen from JIS(Japanese Industrial Standards) in order to explain the proposed procedure. Suggested procedure explains that three dimensional model of equipment is generated by parsing the pre-defined attributes after the entities of part masters is stored in database.

  • In this paper, we have been concerned with development of plastic mold design system by using Auto CAD. We provides a interface and interaction for mold designer who can select optimal mold base and mold parts within Auto CAD environment. We use the paramatric design method and an essential elements group forms. This program made for using Visual Lisp, DCL and Visual Basic that could easily get a database which is built to mold base and parts within Auto CAD. We provide 6 types mold base and 35 parts database for designer. In addition, it will be lined to mold cost and not only 2-D but also 3-D models

  • The design methodology of injection molding die has been changed from two-dimensional drafting to three-dimensional solid modeling, which is due to many advantages over the conventional methodology in terms of design modification and data associativity. In addition to the solid modeling capability, it is required for a mold designer to utilize a database management system that facilitates efficient mold design. In the paper presented is the implementation of a software program which automatically generates three-dimensional mold-bases including standard parts and slider parts, conforming to given geometric constraints. It is based on a commercial CAD system (Unigraphics NX) along with related API (application program interface) libraries. The research is expected to reduce design efforts and simplify construction of a complex three-dimensional mold-base model that is comprised of standard parts and slider parts, by use of the three-dimensional database and automatized geometric dimensioning.

  • In the development of large complex assembly, most design changes are from the following reasons.: 1) insufficient consideration of assembling sequence of downstream process. 2) interference and fit-up of related parts. 3) initial design changes which are not completely resolved. In order to reduce the first reason of above, the assembly-centric modeling methodology was proposed in the part (1) of the thesis. In this part (2), a Digital Mock-Up system, which is a tool to build a virtual mock-up in design stage, has been developed in order to prevent the other two reasons. The system can build a virtual assembly in various ways as followings.: 1) assembling parts which are located in user defined envelope. 2) assembling parts with the specified disciplines. 3) assembling parts that are selected in the part list. It can also make an assembly by the combination of above methods. In addition to that, it has the functions to read/write the virtual assembly and to explode parts of the assembly in desired direction. With the virtual assembly, engineers can design interference free parts without making physical mock-up. The system has been implemented with Oracle database management system in CATIA environment.
