초록

When impeller machining needs to be machined over a length in order to avoid interference with neighboring surfaces between material and tool, there are no databases about cutting condition according to tool slenderness ratio. So selection and machining of cutting condition depends on expert’s experience. Therefore, the purpose of this paper is deciding cutting condition in roughing and finishing process of impeller according to slenderness ratio of AL7075’s end-mill that is the most commonly used for impeller. We have tested for about relation between Slenderness ration and fluctuation width of the cutting force, surface roughness and depth of cut ratio to observe cutting characteristics according to slenderness ratio. The experiments of cutting characteristics and processing criteria are compared with AL5052 which is existing information.
