This paper describes a sweeping path planning algorithm for an autonomous smearing robot on commercial autoCAD system. An automatic planner generates a sweeping path pattern by proposed five basic procedures, (1) interfacing architectural CAD system, (2) off-line obstacle map building, (3) scanning the whole workspace for subgoals of sweeping line, (4) tracking sequence of the subgoals, and (5) obstacle avoiding. A sweeping path is planned by sequentially connecting the tracking points in such a way that (1) the connected line segments should be crossed, (2) the total tracking points should be as short as possible, (3) the tracking line should not pass through the obstacle. Feasibility of the developed techniques has been demonstrated on real architectural CAD draft.

A feature is well known as a medium to integrate CAD, CAPP and CAM systems. For a part drawing including both simple geometry and compound geometry, a process plan such as the selection of process, machine tool, cutting tool etc. normally needs simple geometry data and non-geometry data of the feature as the input. However, a extended process plan such as the generation of process sequence, operation sequence, jig & fixture, NC program etc. necessarily needs the compound geometry data as well as the simple geometry data and non-geometry data. In this paper, we propose a feature data model according to the result of analyzing necessary data, including the compound geometry data, the simple geometry data and the non-geometry data. Also, an example of the feature data model in milling process planning is described.

Recently, the Z-Map model has been used widely to represent the three dimensional geometric shape and to achieve the cross-section and point evaluation of the shape. In this paper, the CNC cutting planning and simulation modules for product with three dimensional geometric shape are realized based on the Z-Map model. The realized system has the various capabilities related to the automatic generation of tool path for the rough and finish cutting processes, the automatic elimination of overcut, the automatic generation of CNC program for a machining center and the cutting simulation. Especially, the overcut-free tool path is obtained by using the CL Z-Map models which are composed of the offset surfaces of the geometric shape of product.

2개이상의 조직에서 전략적인 관계의 일부분으로 컴퓨터를 기반으로 한 운영시스템을 조직간 정보시스템(inter-organizational system: IOS)이라 부른다. 이러한 IOS시스템은 기업간의 업무처리적 활동을 자동화하는 것을 주된 목적으로 한다. 선행연구결과 IOS구축계획과 관련된 적당한 Tool을 개발하는 것은 힘든 작업이며 이와 같은 Tool을 검증하는 것은 오랜 기간에 걸친 많은 실증적 연구를 필요로 하는 것으로 나타났다. 본 연구는 이러한 점을 감안하여 IOS구축개발과 관련된 방법을 개발하기 위하여 계획수립에 지침이 될 수 있는 요인들에 대해 IOS구축기업을 대상으로 실태연구를 수행하였다. 본 연구는 이러한 연구목적을 위하여 IOS구축계획과 관련된 활동, IOS구축계획수립으로 인한 이득 및 IOS계획수립상의 어려움 등과 같은 요인들에 대해 실증적 연구를 수행하고자 한다. 이와 함께 IOS구축계획의 추진방법 및 IOS계획수립에서 외부참여자의 참여 등과 같은 요인들에 대해서도 병행하여 연구하고자 한다. 이와 같은 연구결과를 통하여 IOS구축계획을 효율적으로 구축할 수 있는 요인들을 파악하여 IOS구축계획을 좀더 효율적으로 수립할 수 있을 것이다.

Rural landscape is an outcome of residents' life activity based on natural environment. Unlike city, rural residents make their own landscape over a period of time interacting with nature through cultivating and building houses and huts based on the background. Therefore, residents' role in rural area is of greater importance than city's and their recognition of landscape is a key factor to evaluate and manage rural landscape. Landscape Evaluation Map which utilizing Feeling Map method is a evaluation tool to [md out residents' recognition of landscape. In this tool, responses evaluate landscape around their living space and mark color dots which mean landscape grade on a map. This research is to examine effectiveness and applicability of the tool, Landscape Evaluation Map, which is recommended to estimate residents' evaluation of landscape. Through analyzing 7 cases of field application, the effectiveness of Landscape Evaluation Map has been verified and also demerits have been drawn. After modifying detailed techniques and developing resident education, Landscape evaluation map could be applied to [md out landscape resources rather than to evaluate whole rural landscape.

In order to prevent the production defects the optimum design of product, jig and fixture putting in the field is very significant manufacturing method. Drilling Jig is the device according to industrial demand for multi manufacturing products on the growing at alarming rate. In the field of design and making for machine tool working, welding, assembling with jig and fixture for mass production is a specific division. They require analysis of many kinds of important factors, theory and practice of machine tool operating process and jig & fixture structure, machining condition for tool making, tool materials, heat treatment of jig & fixture components, know-how and so on. In this study we designed and constructed a drilling jig of mass production and performed tryout under the Auto CAD, Auto Lisp database, that we made by database, and window environment. Especially this study is reveals with the analysis of part drawing, jig planning, jig design etc, and then the result of drill jig's making try out.

The objective of the proposed study is to produce a tool-condition monitoring (TCM) strategy that will lead to a more efficient and economical drilling tool usage. Drill-wear monitoring is an important attribute in the automatic cutting processes as it can help preventing damages of the tools and workpieces and optimizing the tool usage. This study presents the architectures of a multi-layer feed-forward neural network with back-propagation training algorithm for the monitoring of drill wear. The input features to the neural networks were extracted from the AE signals using the wavelet transform analysis. Training and testing were performed under a moderate range of cutting conditions in the dry drilling of steel plates. The results indicated that the extracted input features from AE signals to the supervised neural networks were effective for drill wear monitoring and the output of the neural networks could be utilized for the tool life management planning.
