Pattern and Direction Based Smoothing Methods for Surfaces Modeling of Integral Impeller

Abstract:

Integral impeller is a key part of engine, and its 3D modeling of the blade is difficult in the impeller design, which is also an important factor that affects engine performance. Aimed at improving the poorer quality of blade surface machined by five-axis NC machining center, the smoothing methods in which curves and surfaces are accordingly divided into different pattern and direction are presented on the basis of UG. Smoothing results of the surface modeling and the quality of integral impeller blade in actual machining are increased significantly. The experiment shows that the method is convenient and effective to improve blade surface quality and meet the demand of practical engineering.
