Research of Integrated Impeller Modeling and Five-axis Machining Technology based on Reverse Engineering

Abstract

Five-axis NC technology and reverse engineering provides critical support for industrial development and has been an important subject for scholars to study. This paper focused on aviation impeller and discussed the integrated application of NC machining technology and reverse engineering. It collected the shape point cloud data of the impeller through 3D scanner and Geomagic Wrap software and completed the reverse parametric modeling using Geomagic Design X software. The impeller model is complicated in structure which is hard to machine on three-axis and four-axis machine tools, hence developed a five-axis machining program by using the NC programming software of Hypermill and carried out actual machining test. The results showed that the error between the machined sample and the research model is less than 0.05 mm, which can satisfy engineering requirements. It also indicated that the NC program developed by Hypermill software has high machining accuracy and safety, and the integration of reverse engineering and five-axis technology presents positive significance to the innovative design and machining for complicated engineering surfaces.
