中文摘要	Machining complex freeform surfaces more efficient and more flexible has been a challenging task. The equivalent normal curvature milling model is a new milling method proposed in this paper based on 5-axis CNC bed-type horizontal milling machine. At the same time, a specialized whirlwind milling tool is also introduced. The tool path planning of this new milling method emphasizes the alignment of milling tool orientation so as to approach to the surface being machined in the form of equivalent normal curvature envelopment. So this new method will minimize the difference of normal principal curvatures between the surface being machined and the symmetric rotational surface of the milling tool and improve the metal removal rate (MMR). The new whirlwind-milling tool with circular standard-sized cutters is easy to enhance the cutting finish and productivity. The cutter path description and machine-tool coordinate transformation are analyzed, and some examples about this new equivalent normal curvature milling method are discussed.
