Φ70integral impeller and 3D modeling of five axis NC machining
Abstract: Integrated impellers are a kind of representative parts with relatively normal shape of the complicated thin-walled which is usually used for turbine machinery equipment. The design of the working surface relates to several comprehensive subjects such as aerodynamics, hydrodynamics and so on. So the manufacture means,manufacture precision and manufacture quality of the surface all have large effect on the capability parameters. Synthetically considering the characteristic of integrated impeller and the feature of 5-axis High Speed Cutting technology, and the correlation analysis of integrated impeller CAM programming and postprocessor. First, in three dimensional design software UG environment, modeling the integrated impeller's blade and hub respectively, emphasizing analysis
the method of modeling the blade surface, for subsequent 5-axis High Speed Cutting ready to work. Then analyze the 5-axis CNC High Speed Cutting technology thoroughly, Accordingly, planning a integrated impeller 5-axis High Speed Cutting process scheme. Finally in UG CAM function module of integrated impeller blade surface and runner surface respectively, while check and simulation integrated impeller's manufacturing process repeatedly, And analyze the postprocessor for the actual CNC machining. Make a good foundation for the actual CNC machining of integrated impeller.
