5축 Machining Center를 이용한 스플리터가 있는 임펠러 가공에서 공구경로 생성에 관한 연구

The process of impeller 5-axis machining is presented. The tool path planning consists of roughing and finishing. The cutting tool path is generated on machining efficiency and impeller type. The cutting area can be divided into three regions in a splitter type. The tool of the maximum size is selected for each divided region. Interference can be avoided by checking the intersection of the cutting tool and ruling. In finishing the blades, hubs, and leading edges are machined. The blade can be finished with side cutting and the hub being machined in an iso-parametric path. The one-way point milling method is used for finishing the edge.
