Three-dimensional (3D) computed tomography image models are helpful in reproducing the maxillofacial area; however, they do not necessarily provide an accurate representation of dental occlusion and the state of the teeth. Recent efforts have focused on improvement of dental imaging by replacement of computed tomography with other detailed digital images. Unfortunately, despite the advantages of medical simulation software in dentofacial analysis, diagnosis, and surgical simulation, it lacks adequate registration tools. Following up on our previous report on orthognathic simulation surgery using computer-aided design/computer-aided manufacturing (CAD/CAM) software, we recently used the registration functions of a CAD/CAM platform in conjunction with surgical simulation software. Therefore, we would like to introduce a new technique, which involves use of the registration functions of CAD/CAM software followed by transfer of the images into medical simulation software. This technique may be applicable when using various registration function tools from different software platforms.

NC machining of large screw which is usually used as a part in an extruder for injection molding is done on 3-axis turning machine, and it is very time-consuming process. Not only in machining but in preparing part program for a NC machine, it requires very long time because the shape of the screw is not easy to model when using an existing general CAD/CAM software even though it is workstation level software. In addition, tool path generation procedure for NC turning for screw shape is also very tedious one because large amount of data for cutter location point must be produced and there is no specific CAM software for the machining. In this paper. development of a CAM system for screw machining which saves the role of CAD software by use of menu driven data input system for various screw shapes is introduced.

Machine element design is a very important course in the undergraduate program of mechanical engineering in that it presents traditional design concepts. While computer aided design(CAD) receives more attention, students tend to ignore the machine element design or traditional design concepts. However, design methodologies related to machine elements are utilized quite often in practical fields. Also, design methodologies provide good insight for the decision making process of modern design. Generally, CAD is used for simple drafting without the real design process in the undergraduate program. Design software has been developed for various machine elements. Through menu display, a user can select or furnish the design input such as design objects, dimensions, environmental forces and usages, and safety factors. Then the software carries out the design processes which are the same as those of textbooks. The result of the design is filtered to have the values in the standards. The designed machine element is drawn via commercial CAD software. The software has been developed with C language on a personal computer. The developed software is being utilized successfully in a design course, and the experiences are discussed in this paper. The software can be used in industries which require the repeated process of the machine element design.

In this paper, the Post Process for the manifold complex processing using CAD/CAM Software of two and a half Dimensions(2.5D) has been developed to maximize the application of the manifold manufacturing machine. Many companies are currently making use of high price systems to improve manufacturing process using the multi-axial complex manufacturing machine. In accordance with the requirements, the utilization of CAD/CAM Software for the manifold complex manufacturing machine is earnestly demanded. However, the experts who have experience in manifold manufacturing machine are insufficient. Consequently the outcomes of the Post Process for 2.5D CAD/CAM Systems have been dealt in order to be smoothly operated by those who have basic skills and be understood in process drawings. CNC program functions can be specially used as they are, when drawn up. The Post Process for the original point designation and transformation of coordinates has been developed and applied. The results gave proof of practical manufacturing outcomes.

For the development of automobile lighting components, various designers, developers and manufacturing personnel are involved, each group needing different software tools. In this Smartlite project, several software tools were developed far product development of the lighting components and then tested using two different user interfaces (UIs); the first was based on a commercial CAD system (SDRCI-DEAS) and the second was based on a web browser. The specific focus of this study was a comparison between the new web-based UIs, and the UIs on commercial CAD systems. The usability data have been collected from the users at Visteon and showed that the web-based UIs provided comparable functionality with the CAD-based UIs in terms of performance and usefulness. For the criteria of accessibility, the web-based tools out-performed the CAD-based tools.

최근 국내 건축시장에서는 건설프로젝트 생애주기 전반에 걸쳐 생산되는 정보를 3D 모델 기반으로 관리하는 BIM에 대한 관심이 높아지고 있다. 국가적으로도 그에 따른 정책, 기술개발의 진행과 함께, BIM을 이용한 설계기준이 제도화 되고 있다. 그러나 BIM 소프트웨어(Revit Architecture)를 이용한 2D 설계도면 작성과 관련해서는 기존의 CAD와 같은 수준의 실시설계도면 작성이 어려운 것으로 인식되고 있다. 기존 연구에 따르면, BIM 소프트웨어가 가지고 있는 문제점으로는 시공수준의 접합상세가 나오지 않는다는 문제점과 효과적으로 상세를 더할 수 있는 모델링 기능이 부족하다는 문제점이 지적되고 있다. 이에 본 연구에서는 BIM 소프트웨어를 사용하여 현재 납품되고 있는 2D 실시설계도면 수준의 도면작성과 출력가능 여부를 검증하고자 한다. 이를 위해 설계기본요소를 분석하고, 단면상 세도를 사례로 BIM 소프트웨어에 제공되는 기능을 사용해 기존 CAD로 작성한 실시설계도면과 동일한 수준의 도면작성과 출력이 가능함을 검증하였다.

A product is designed through the collaboration among engineers in several fields such as design, analysis, and manufacturing. These series of functions are performed repeatedly during the design process. An easy access and exchange of the model data is one of the important elements that help to shorten production development time. Especially, the importance of data exchange between CAD and CAE applications is increasing in the field of verification and estimation of the products. However, information and knowledge of model which is generated by a CAD software cannot be transferred by a function of CAE software, as an exchange of product data between CAD and CAE applications. It causes a delay in design analysis and eventually discourages a designer's effort in improving his design. Therefore, we need to integrate a commercial CAD and CAE applications effectively and to use the same interface on a product model obtained in a distributed environment. This paper shows how to implement a model exchange between CAD and CAE by a web-service and how to provide a communication environment among engineers.

CAD/CAM 관련 자료들을 살펴보면 현재 국내에서 유통, 판매되고 있는 CAD S/W는 30여 가지에 이른다. 이렇게 많은 제품들이 각각의 장, 단점을 가지고 사용자들의 선택을 위해 계속적인 기능 향상을 앞다투고 있다. 이 때문에 물론 선택의 폭은 넓어졌지만, CAD S/W를 처음 도입하거나 기존에 사용중인 S/W를 교체하고자 하는 사용자들은 이렇게 다양한 제품 중에 어떤 것이 가장 적합한 것인가를 결정하기 위하여 많은 노력이 필요하게 되었다. CAD S/W는 그 가격과 기능의 다양함 뿐만 아니라, 일단 한 제품을 사용하는 것으로 결정한 후에는 다시 교체하기 위하여 많은 시간과 노력을 필요로 하기 때문에 그 평가와 선정작업은 매우 중요한 부분이라고 생각된다.
