  • In order to implement Artificial Intelligence, various technologies have been widely used. Artificial Intelligence is applied for many industrial product and machine tools are the center of manufacturing devices in intelligent manufacturing system. The purpose of this paper is to present the construction of Rule Base for knowledge structure that is applicable to machine tools. This system is that decision whether to act in accordance with machine status is support system. It constructs Rule Base of knowledge used of machine toots. The constructed Rule Base facilitates the effective operation and control of machine tools and will provide a systematic way to integrate the expert's knowledge that will apply Intelligent Machine Tools.

  • 본 연구에서는 광 픽업의 소형, 경량 제작을 위해 MEMS 기술을 이용하여 planar micro optics 방법으로 광 픽업을 구성하는 micro lens, actuator, beamsplitter 등을 설계, 제작하고 집적화한 픽업헤드를 구성하여 그 특성을 분석하였다. 특성분석 결과 disk에 focusing 되는 beam의 형상은 circle type의 비교적 양호한 결과를 얻을 수 있었고 beam spot size는 약 22$\mu m$로 실제 system에서 요구되는 0.9$\mu m$이내의 beam spot size에 비해 약 25배 가량 큰 beam spot size를 얻을 수 있었다.

  • Recently the machining technique have been progressed rapidly according to developments of the product technique in the machine tool and new tools. But in the case of vertical machine center(VMC), to become visible there is the appearance of bending because of the structural problems of x-axis guide way, and this would effect directly on accuracy of form of the straightness, parallelism and flatness. In this paper, I purpose to check the appearance of bending with the experiment and improve the working accuracy. Under the constant working conditions, the appearance of bending of x-axis guide way was measured to confirm the effectiveness of the compensation method in the vertical machine center(VMC). By using this method the results show that the accuracy of form of the straightness, parallelism and flatness could be reduced to 20% compared with ordinary method.
