摘要：          A multitude of freeform surface products utilized in aerospace or shipbuilding industries are manufactured to satisfy the desirables of specific physics and kinematics functions. Therefore, the corresponding milling mode should be carefully designed with indispensable consideration of both the geometry and functionality of the product.   This presentation will first give an overview on recent development in tool path generation that aim to address the manufacturing efficiency challenge. In particular, we demonstrate computational fluid dynamics could present an opportunity for generating milling tool paths along the streamlines of flow directions. Further, the constant scallop machining and the directions with maximum strip width is also employed, which could optimize a more efficient initial tool path from a slice of feasible streamlines. A compressor blade simulation and machining result demonstrates the possible advantages of the proposed method.
