A conversational programming system for turning processes was studied to enhance the user friendliness of a NC Lathe by adopting man-machine interface functions through Delphi programming tool under the Windows 95 environment. Functions of tool collision checking were developed through zone limitation algorithms. Final shape of workpiece was generated by means of tree structure algorithm. Shop floor programming performance was incorporated in the developed CAM module. In order to increase flexibility of the man-machine interface, graphic based programming tools have been developed. A NC turning machine equipped with an open architecture PCNC was used as a test bed of the system. Performance of the system was verified through case studies.

텐지블 프로그래밍 도구는 그래픽 인터페이스 기반의 프로그래밍 방식과는 달리 컴퓨터를 사용하지 않고 손으로 조작하여 프로그래밍 할 수 있는 도구이다. 어린학생을 대상으로 알고리즘을 설계하고 시뮬레이션 하는 경험을 제공하여 논리적 사고 능력을 향상시킬 수 있다. 본 연구에서는 기존에 개발된 텐지블 프로그래밍 도구를 분석하여 도출된 문제점을 수정 보완하기 위해 다수의 명령어를 하나의 블록에 맵핑, 즉시적인 결과 확인, 다양한 수준의 알고리즘 표현이 가능하도록 설계 후 B-Bricks를 개발하였다. 개발한 B-Bricks를 초등학교 4-6학년 29명을 대상으로 적용한 결과, 문항의 난이도가 상승할수록 정답률이 감소하고 문제풀이시간이 증가하는 것으로 분석되었다.

A pre-processing program based on the OOP(object-oriented programming) concept has been developed. The program consists of the input of a 2D or 3D flow problem to a CFD program by means of an user-friendly interface and the subsequent transformation of this input into a form suitable for the solver(PowerCFD) using unstructured cell-centered method. User-friendly GUI(graphic user interface) has been built on the base of MFC(Microsoft Foundation Class). The program is organized as modules by classes based on VTK(Visualization ToolKit)-library, and these classes are made to function through inheritance and cooperation which is an important and valuable concept of object-oriented programming. The major functions of this program are introduced and demonstrated, which include mesh generation, boundary settings, solver settings, generation of grid connectivity and geometric data etc.

최근 초등학생을 대상으로 다양한 교육용 프로그래밍 언어와 교수학습방법이 개발됨에 따라 교육현장에서 활발하게 프로그래밍 교육이 이루어지고 있다. 그러나 대부분의 프로그래밍 교육이 초등학교 고학년 학생을 대상으로 하고 있으며, 문제해결과정 보다 도구의 사용법에 중점을 두고 있어서 정보교육 전반에 활용되기에는 한계가 있다. 정보교육에서 프로그래밍 활동이 활발히 이루어지기 위해서는 학습대상을 넓히고 교육내용을 사고력 측면에서 고려할 필요성이 있다. 따라서 본 연구에서는 초등학교 저학년 학생도 쉽게 사용할 수 있는 프로그래밍 도구와 사고력 향상을 중심으로 하는 프로그래밍 과제를 제안하였다. 프로그래밍 도구는 텐지블 유저 인터페이스(Tangible User Interface, TUI)를 기반으로 초등학교 저학년 학생도 쉽게 사용할 수 있도록 하였으며, 프로그래밍 과제는 로봇을 활용하여 논리적 사고를 향상시키는 목적으로 개발하였다. 실험을 통해 텐지블 프로그래밍 도구가 초등학교 저학년도 쉽게 사용할 수 있는 도구적 사용성을 나타내었고, 개발한 과제 또한 논리사고력 향상에 효과가 있음을 보여주었다.

This paper describes a development of conversational program for lathe. The proposed program is a NC programming system specialized for use in machine tool controls. Its easy to use graphic interface built-in database capabilities make it an ideal way to program part on the shop floor. In order to manage effectively machining process it proposed the algorithm of tree structures for design processing. Also using interative structure it proposed the methods of conversational programming to generate automatically NC program.

In this study, an automation tool was developed for rapid evaluation of machine tool spindle designs with automated three-dimensional finite element analysis (3D FEA) using solid elements. The tool performs FEA with the minimum data of point coordinates to define the section of the spindle shaft and bearing positions. Using object-oriented programming techniques, the tool was implemented in the programming environment of a CAD system to make use of its objects. Its modules were constructed with the objects to generate the geometric model and then to convert it into the FE model of 3D solid elements at the workbenches of the CAD system using the point data. Graphic user interfaces were developed to allow users to interact with the tool. This tool is helpful for identification of a near optimal design of the spindle based on, for example, stiffness with multiple design changes and then FEAs.

A post-processing program based on the OOP(Object-Oriented Programming) concept has been developed for flow visualization of the flow analysis code(PowerCFD) using unstructured cell-centered method. User-friendly GUI(GTaphic User Interface) has been built on the base of MFC(Microsoft Foundation Class). The program is organized as modules by classes including those based on VTK(Visualization ToolKit)-library, and these classes are made to function through inheritance and cooperation which is an important and valuable OOP concept. The major functions of this post-processor program are introduced and demonstrated, which include mesh plot, contour plot, vector plot, surface plots, cut plot, clip plot, xy-plot and streamline plot as well as view manipulation (translation, rotation, scaling etc).

In this paper, we developed a Windows 95 version off-line programming system which can simulate a track vehicle model in 30 graphics space. The track vehicle was adopted as an objective model. The interface between users and the off-line program system in the Windows 95's graphic user interface environment was also studied. The developing language is Microsoft Visual C++. Graphic libraries, OpenGL, by Silicon Graphics, Inc were utilized for 3D Graphics.
