The impeller is the core part of a turbomachinery such as a generator, turbo charger, compressor, turbo engine and jet-engine. This study presented an efficient roughing method of machining impeller. The method consists two categories. One is selecting optimal tool radius and tool attitude by dividing cutting area into two regions to reduce cutting time. The regions are determined by character point on the geometry of impeller blade. The other is avoidance of tool interference. Tool interference in cutting areas is avoided by checking the intersection between cutting tool axis and ruling line on blade surface.

This paper proposes a tool path generation method for machining impellers with 5-axis machining center. The shape of impeller is complex, being composed of pressure surface, suction surface and leading edge, and so on. The compound surface which is made of ruled surface such as pressure surface and suction surface and leading edge such as fillet surface, makes the tool path generation much complicated. To achieve efficient roughing, cutting area is divided into two region and then tool radius of maximum size that do not cause tool interference is selected for shortening machining time. In finishing, accuracy is improved using side cutting for blade surface and point milling for leading edge.
