  • 전동기는 전기 에너지를 이용하여 회전축에서 기계적 회전력(토크)을 얻는 장치이다. 많은 응용분야에서 평균 토크를 제어하는 것만으로도 충분한 제어 성능을 얻을 수 있지만 로봇. 수치제어선반 등과 같은 정밀 제어 분야의 경우 전동기의 순시 토크를 제어하여 속도 및 위치를 제어하여야 한다.(중략)

  • The feature based modeling approach is useful for post-CAD related works such as process planning and NC part programming. This paper describes the development of 'FeaTURN' system which is feature based NC part programming system for turning operation. The programming task in 'FeaTURN' system becomes easy and effective with the assistance of feature icons. The manufacturing attributes can be handled toghther with the features during input procedure. The cutter location data (CLD) is determined by the processor module. The post process module converts the CL data to machine control data (MCD). Also, the system graphically displays the tool path.

  • Ball screws are used in the feeding system for transmission of driving force. The friction effect between bed and table, which can affect in accuracyin one dimension feeding and describe the dynamic feeding error, could be simplified as a specific model through experiments. The experiments for dynamic feeding errors were performed om tje NC lathe eith a ball screw. The errors in feeding were measured with respect to the variances of feed, spindle speed and motor current for feeding. A rotary encoder and a current sensor were installed with NC lathe.

  • In this paper, the motion of ballscrew and shape of workpiece are the main objective variables varying with load conditions. To verify feed mechanism in NC lathe, the monitoring system is designed and cutting condition variables are spindle speed depth of cut and feed. During machining, rotation number of ballscrew motion of ballscrew in direction to gravity center and cutting force are measured. After machining, the roughness of workpiece is measured.

  • This paper proposes a study on the spherical lens manufacturing by simultaneous 3 axis for NC lathe. We use friction drive system for moving system in experimental diamond turing machine. The diamond turning machine use manufacturing for high quality lens, mirror and many optics products. Especially, the high tech industry require a lot of lens. For example, optical engineering. medical science, space engineering and material engineering etc. The friction drive system is very simple and quiet, compared to ball screw system. We find a problem at the simultaneous 3 axis and suggest a solution. Also, when we manufactured a micro lens. find a problem and solution.

  • The pupose of this study is the development of CAM system which can cut any shape by CNC lathe.. The overall goal of the CAM system is to achieve the CNC lathe machining, form roughing through to final measuring. The hardware of the system comprises PC and CNC lathe. There are three steps in the CNC lathe machining, (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 can conduct a micro CAM system in the PC without economical burden.

  • Recently, for enhanced productivity the induction of CAD/CAM is vigorous. Most of high-level CAD/CAM systems produce powerful faculties. But it is very expensive to purchase the system in small and difficult to be operated by non-experienced workers effectively. Then the resonable CAM system for these is needed. In this study we developed a proto-type of the CAM system for CNC lathe connecting with personal computer. This system is configured with interactive menu windows for easy control of CNC lathe. And the system supports tool path generation for cutting conditions of workpiece. The performance of this system is satisfactory.
