라인센터용 공작기계 베드의 구조해석에 의한 설계개선

This study analyzed static and dynamic characteristic of the structure of machine tool by CAD/CAM, and improvement plan of the basic performance was proposed Designed machine tool is line center BC-SOD, and the maximum speed is 4000rpm, and X-stroke is 800㎜ Mam got result is shown with the execution of 3D modeling and structure analysis and vibration simulation in the following Center of gravity amount of change are X direction 256㎜, Y direction 127㎜, Z direction 34㎜ In comparing with the weight of the erection from the result, It seems to safety The result of vibration simulation of Main bed arose in 8465rpm first mode shape This seems to be to safety as mam bed, since the largest use machining speed of bed is 4000rpm
