  • In ship building industry, CNC and CAM are mostly applied to NC cutting and manufacturing of propeller and prototype ship model. Herein, prototype ship model is producted by CAD/CAM process. Hull form data is obtained from the ship drawing and used for 3D modeling by CAD software Pro/Engineer. CAD data is transferred into CAM s/w SPEEDplus to perform CNC process and the prototype small ship model is manufactured by CNC machine. To solve data transfer among different systems. IGES and STEP neutral formats are currently used. Herein IGES format is adopted for data transfer between CAD/CAM softwares.

  • Cam mechanisms are one of the most popular devices for generating irregular motion and are widely used in many automatic equipments, such as textile machinery, internal combustion engines and other automatic devices. In order to obtain the positive motion of follower by rotating cam, its shape should be correctly designed and manufactured. In present paper, a CAD/CAM system is developed for shape design of disk cams using relative velocity method and NC code generation using the biarc curve interpolation. And, a disk cam is successfully manufactured by the developed CAD/CAM system. Thus, it is shown that the developed CAD/CAM system can be used for high precision cam profile CNC grinding machine.

  • In recent years, precision machining of the dental prosthesis by computer assisted system is becoming pervasive in clinical dentistry. Prosthesis fabricating system that is designed by computer software and made by computer devices is called as a CAD/CAM (Computer-Aided Design/Computer-Aided Manufacturing) system. By the use of dental CAD/CAM system, the improvement of marginal compatibility and mechanical properties in prosthesis can be obtained more effectively, an aesthetic quality by using new materials such as zirconia can be increased. Also, the restoration process can be simple and efficient, the production time can be shortened, the process of manufacture can be standardized, and the mass production is possible. What is clear is that these benefits are theoretically possible, but the dentist or dental technician must understand the CAD/CAM basic principles and limitations for obtaining the maximum advantages of CAD/CAM system. For this reason, this article will be presented about the basic principles of CAD/CAM system and the factors of error that might occur in the CAD/CAM process based on my empirical study.

  • 80년대부터 국내에 도입된 CAD/CAM시스템은 금형 및 관련 제조업체, 자동차 제조업체, 플랜트 /조선업체 등에서도 제도, 설계 및 설계해석용, CAM을 이용한 NC 가공용 등으로 적용되고 있다. 그러나 CAD/CAM 시스템을 판매업체의 불충분한 교육과 아프터 서비스가 아직 미흡하여, 시 스템 사용업체의 경우 시스템 활용기술 부족, 기술인력 부족 등의 이유로 활용도가 높지 못하다. 그럼에도 불구하고 많은 업체들이 CAD/CAM 도입을 본격적으로 준비하고 있으며, 93년의 경우 90년에 비해 사용자수가 2배가 되리라는 전망이다. 많은 업체의 경우 인원절감, 시간단축, 경비 절감 등의 비용효과와 정밀도/정확도 효과 등의 업무수준 향상 효과를 기대하며 추진하고 있으나 표준화, 관리의 체계화 효과 및 기업이미지 개선, 직원의식 수준 향상 등의 상징적 효과도 크다고 볼 수 있다. 국내에 CAD/CAM 시스템 보급을 촉진하기 위해서는 소프트웨어의 한글화 작업이 이루어져야 하고 분야별로 다양한 데이터베이스가 구축되어야 할 것이며, 가격이 저렴하고 속 도가 빠른 형상 모델링 기술발전이 요구된다. 끝으로, 우리 실정에 맞는 CAD/CAM 소프트웨어의 국산화 작업이 우리가 풀어야 하는 최대 과제라 할 수 있다.

  • In order to increase the modeling power and productivity of CAD/CAM systems, demands for customization of CAD/CAM system increased. Customization of a CAM system involves making it easier to learn and use, adding new modeling features not supported in a general purpose CAM system, and providing parametric inputting mechanism. A customization from a commercial CAM system (OMEGA) has implemented for two dimensional free curve CNC glass scribing machine of medium size company in Cheonan. A CAD technician who has no CAM experience can operate this customized CAM system satisfactorily.
