  • In this paper, we demonstrate the implementation case using component based development tool under development process for application developments. The tool suggested provides the programming environment for the development of distributed manufacturing applications primarily. The development tool is classified into visual component, logic component, data component, knowledge component, neural net component, and service component which is a core component for the support component edit and execution. We applied the tool to the domain of the design and routing plan to retrieve existing similar design models in database, initiate a model, generate a process plan, and store the new model in the database automatically. Utilizing the tool, it integrates a geometric modeler, engineering/manufacturing database, and knowledge sources over the Internet.

  • The main purpose of this study was to develop a program outcomes assessment tool using reflection journal. Reflection journal has recently come to gain more attention from school as an alternative assessment tool. Although numerous studies reconfirmed the educational importance and value of reflection journal as an assessment tool, research on the assessment tool of the engineering accreditation, based on education view is scarce. After literature reviews about the case studies on the program outcomes assessment, this study, to analyse the current assessment tools, and then, examined the educational implications of reflection journal as a program outcomes assessment tool. This study suggested the assessment tool using reflection journal for PO6 (teamwork) and PO11 (engineering ethics), one of the most important assessment items in engineering accreditation. In this study, we used the performance criteria, assessment criteria, rubric, and closed the loop to measure the teamwork and engineering ethics. The result of this study is significant in terms of guiding the future evaluation system development for program outcomes.

  • Machine tool (Mother machine) is the basis of industrial development and it largely has an effect on the quality improvement and Productivity improvement of machinery products because it demands high technical abilities such as design, machining. control and assembling which reflect the technical level of a country. But, in case of domestic companies. it is difficult to secure good engineers and enough fund for developing machine tool, which can not narrow the gap with advanced machine tool manufacturing companies. Therefore, this Project focused on the extraction of research and development project to improve the international competitiveness of machine tool industry through comprehending problems that domestic companies have and investigating the research trend in domestic and international countries.

  • This study has been performed to present a new automatic tool wear measurement by digital image processing. The purpose of this paper is to develop an automatic tool wear measuring system based on the image processing which can be applied to the quasi-real time measurement of the characteristics of insert tip in turning. Tool wear monitoring is one of the key-problems, for the development of control systems of modern unmanned factory which are not completely solved now. In oredr words at present complete qualitative and quantitative information on tool wear morphology is required, at least on the following aspects : flank wear, its dimensions and distribution on the maximum and mean values on VB pqrqmeter in the various zones of the wearland. crater wear, its main dimensions and values of KT parameters. This research has been performed to this technique made possible by designing a proper lighting system to the worn tool with following features : The flank wear is measured by observing the active cutting part from a proper direction and by lighting the wearland by a diffuser optic system. The crater wear is visualized by lighting the tool by a He-Ne gas laser system developed in this study. By means of this system it is research to evaluate classical parameters of tool wear and to have complete information about tool wear morphology.

  • Intelligent Decision System support the decision analysis process in the managerial problems with decision analytic knowledge as well as domain specific knowledge. Influence Diagram has been one of the major knowledge representation in the intelligent decision system. In the development of intelligent decision system, knowledge acquisition is also known to be difficult. This paper suggests a developing tool using an influence diagram and Verbal Protocol Analysis which facilitates knowledge acquision for intelligent decision system. An ennvironmental decision making problem is used as an illustrative example and validation of the suggested developing tool is discussed. The suggested tool is very flexible to be expanded or applied to similar problems.

  • In this research, a tool was developed for the rapid performance of three-dimensional finite element analysis (3D FEA) of a machine tool spindle system made of a shaft and bearings. It runs the FEA with data, such as the bearing stiffness and the coordinates of the points, to define the section of the shaft, bearing positions, and cutting point. developed for the spindle system and then implemented with the tool using an object-oriented programing technique that allows the use of the objects of the CAD system used in this research. Graphic user interfaces were designed for a user to interact with the tool. It provides rapid evaluation of the design of a spindle system, and therefore, it would be helpful to identify a near optimal design of a spindle system based on, say, static stiffness with design changes and, consequently, FEA.

  • In this research, a tool was developed to automate one-dimensional finite element analysis (1D FEA) for design of a machine tool spindle. Based on object-oriented programing, this tool employs the objects of a CAD system to construct a geometric model and then to convert it into the FE model of 1D beams at the workbenches of the CAD system with minimum data to define the spindle such as bearing positions and cross-sections of the shaft. Graphic user interfaces were developed for users to interact with the tool. This tool is helpful in identifying a near optimal design of the spindle with the automation of the FEA process with numerous design changes in minimum time and efforts. It is also expected to allow even design engineers to perform the FEA in search of an optimal design of the machine tool spindle.

  • Simulator is composed of several devices that have a variety of forms and functions. These devices are connected to each other by a network intricately. For this reason, simulator development and maintenance process require a lot of time and money. In order to successfully develop the simulator, it is ideal that related professionals share the work and work together in parallel. However, development is carried out inefficiently, because task interdependence makes it difficult to work in parallel. In this paper, the developments of the simulator were classified into algorithm development and system development, and it was discussed how to lower the interdependence of these two tasks and support professionals. In particular, based on the requirements analysis of the domain experts responsible for the development of the algorithm, we designed the support tool for simulator development and proposed development process using this tool. We also introduced the concept of a DataSet in order to support algorithm development of domain experts and manage data flexibly. And we designed network architecture to enable flexible reconfiguration of simulator equipment. By using the tools to support the simulator development, domain experts are able to concentrate on algorithm development and it is expected to be effective collaboration. In addition, the development plan and management are expected to be easy because the development process is systematic and clearer.
