양희구(Hee-Gu Yang),김석일(Seok-Il Kim),김동룡(Dong-Ryong Kim),김건상(Kun-Sang Kim) 한국자동차공학회 1996 한국자동차공학회 춘 추계 학술대회 논문집 Vol.1996 No.6_1
The ride and handling performances of vehicle have close relation with the driver's safety. In this study, a computer aided testing(CAT) system for measuring and analysing the ride and handling performances of vehicle is developed based on the Windows programming technique. Especially, in order to effectively derive the significant performance parameters from vehicle tests such as J-turn, steady state cornering, lane change, double lane change, slalom and so on, the CAT system has various functions related to real time measurement, time domain analysis, frequency domain analysis, XY domain analysis, steady state analysis, database management and so on.<br/> <br/>

본 연구에서는 확장형 Z-Map모델을 토대로 3차원 제품의 형상설계에서 머시닝센터에 의한 CNC가공까지를 일괄적으로 처리할 수 있는 CAD/CAM시스템을 IBM PC와 Borland C++4.5를 이용하여 Windows환경에서 개발하였다. 3차원 제품의 형상은 기본 입체의 생성기능, 자유곡면형 입체의 생성기능, 평행이동, 회전스위프기능 등과 같은 입체정의기능, 그리고 스플리트기능, 불리안기능 등과 같은 입체조직기능을 통해서 쉽게 설계 및 구형할 수 있다. 또한 제품과 소재의 형상정보, 밀링공구의 제원, 그리고 절삭조건을 토대로 황삭가공과 정삭가공에 대한 공구경로의 자동생성, 머시닝센터용 CNC프로그햄의 자동생성, 시뮬레이션, 표면조도 확인 등과 같은 여러 가지 기능들을 갖추고 있다. 특히 과대절삭이 방지된 공구경로는 밀링공구의 제원과 절삭조건을 토대로 제품형상을 옵셋시켜서 생성한 CL Z-Map모델을 이용해서 도출하였다. In this paper, the extended Z-Map model based CAD/CAM system which is able to process systematically from the three dimensional shape design of products to the CNC cutting of products by the machining center, is realized on the Windows environment by using IBM PC and Borland C++4.5. The three dimensional shape of products can be easily designed and constructed by means of the solid definition functions such as the creation operation of primitives and solids with free-formed surfaces besides the translational and rotational sweep operations, and the solid manipulation functions such as the split operation and the Boolean operation. And the 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, the cutting simulation, and the surface roughness evaluation of machined product. 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.

This study aims at developing the high speed/intelligent machining system using the plug/play method of an open architecture controller. The plug/play technology by the Application Specific Function (ASF), can readily implement the open architecture controller into various machining system or other automatic devices. The plug/play method integrates the ASF, visual builder, controller OS technology. This study, as an example, presents a schematic diagram for integration of an open architecture CNC and individual component technology for the high speed/intelligent machining system.
