  • The purpose of this study is the development of CAM system which can machine and measure any shape by CNC lathe. The overall goal of the CAM system is to achieve the CNC lathe machining, from roughing through to final measuring, The hardware of the system comprises PC, CNC lathe and measuring tools. There are three steps in the CNC lathe machining and measuring, (1) geometric modeling by the shape patterns, (2) NC commands generation by the tool path compensated for tool nose radius, (3) machining and workpiece measuring on the lathe. It is developed a software package, with which we can conduct a micro CAM system in the PC without economical burden.

  • The most important thing in measuring the tool wear is to set up the measurement base. The end mill that is being used for machining of die is difficult to set up the base and to measure the tool wear because of geometric properties of that such as a helix and relief angle. In this study, a new instrument using spindle orientation function in end milling is developed to measure the tool wear and evaluated by the measuring system on the machine. Finally, this new method makes possible the wear measurement of same position and reduces the measuring time compared with the measuring methods such as the microscope and CCD.

  • On-machine measuring system of Numerically Control(NC) machines permit computer control of basic material cutting processes of moulds. A part of mould designed within a CAD/CAM system can be manufactured by generation of tool paths by the measuring systems. Since the three-dimensional geometry by AutoCAD of the part is contained in the data base, the manufacturing specialist combined with the appropriate software simulation, can not only create the commands to drive the virtual measuring and standardization of measuring modules but also can check for mistakes by viewing the computer graphics simulation of the tool cutting sequence.

  • The tool wear that is developed by long-term machining in mold manufacturing with machining center makes a severe influence to the accuracy and the surface roughness. in this reason, tool-wear supervising system which has guaranteed high accuracy and high speed is needed to improve the measurement quality. Touching probe and touch sensor are widely used to measure the tool profile at on-machine measurement. In this paper, using the newly developed electric touch point measuring system, the Automatic Tool Compensation System is developed to correct the error of tool diameter resulted from the wear, and the operating method of this system is also provided.

  • The purpose of this study is the development of CAM system which can cut and measure any shape by machining center and coordinate measuring machine. The overall goal of the CAM system is to achieve the CNC machining, from digitizing through to final cutting. The hardware of the system comprises PC and machining center, CMM. There are three steps in the CNC machining, (1) workpiece measuring on the CMM, (2) geometric modeling by the CAD system, (3) NC commands generation by the tool path compensated for tool nose radius. It is developed a software package, with which can conduct a micro CAM system in the PC without economical burden.

  • Purpose - The purpose of this study is to develop a tool to measure the corporate social responsibility activities of tourism and hotel companies using ISO26000 and to verify its reliability and validity. Design/Methodology/Approach - This study is the development of a tool for evaluating social responsibility activities of tourism and hotel companies. For this, as the first stage filer research, 4 experts developed the questions based on ISO26000. And 12 experts (academia, industry) were surveyed by Delphi to evaluate suitability. Finally, the validity and reliability of the development tool were verified for a total of 55 incumbents and related persons. Research Results - For the development of a tool for measuring social responsibility activities of tourism and hotel companies, based on the standard draft of ISO26000, questions that fit 7 core areas were composed (60 questions). In addition, a Delphi survey was conducted on a panel of 12 experts, and a total of 45 questions were derived. Finally, as a result of an exploratory factor analysis of 55 field experts, 20 items consisting of 6 factors were finally confirmed as a measuring tool for social responsibility activities of tourism and hotel companies. Research implications or originality - It is significant for the first development of a social responsibility activity scale suitable for the situation of tourism and hotel companies by applying ISO26000. This will raise awareness of the importance of social responsibility activities in the tourism industry environment, and will help tourism companies to develop a positive awareness of social responsibility activities and to prepare effective implementation strategies.

  • In general, manufacturing error originated in bad material, machine tool defection, tool defection, and tool breakage. When the manufacturing process is stable, the error is come from the tool wear. In common on-machine measurement, teaching probe and touch sensor are widely used, however in this thesis the automatic tool compensation system using electric touch point measuring system is developed and evaluated, and effective operating is proposed.
