We made to develop CNC Tool Grinding Machine automating the linear motion of X,Y,Z axis of table, and thetilting and rotation of tool holding vice by using Encorder to increase the efficiency of tool grinding for the Conventional Tool Grinding Machine. We did not consider the part of static, dynamic and thermal behavior that must necessary consider when wedesign, because we used existing Conventional Tool Grinding Machine as it is. We investigated simulation to make existing Conventional Tool Grinding Machine like CNC. We also designed it, and we compared the capability of existing Conventional Tool Grinding and CNC Tool Grinding Machine, and we investigated, too.

As tools for machining precision componants, end mills and ball end mills are widely used. For the end mills have longer cylindrical shape comparing dianeter, they are liable to deflect when machining and induce geometrical error and deterioration of surface roughness. To improve the stiffness and the sharpness of the cutting edge of end mill, a software for manufacturing end mills are developed. The program predicts the result of helical flute grinding and the configuration of cuting edge which is located in cylindrical surface. Furthermore to facilitate the manufacturing end mills using CNC grinding machine, the setting condition which satisfy the geometrical requirements like tool rake angle and stiffness are obtained.

최근 CNC 공작기계의 고속화와 고정밀화에 따른 고속가공이 세계적으로 급속히 진전되고 있는데, 우리나라 역시 이러한 추세에 따라 고속가공기의 개발 및 시판이 이루어지고 있으며 금형가공업체 같은 공작기계를 주로 사용하는 업체애도 급속히 고속가공기의 도입이 이루어지고 있다 하지만 고속 가공에 중요한 역할을 하는 엔드밀의 성능이 뒷받침 되지 않는다면 이러한 고속가공기의 발달은 큰 의미를 갖지 못한다고 할 수 있다. 따라서 엔드밀의 개발은 고속가공기술의 도입에 있어서 꼭 필요하다.(중략)
