Three-dimensional modeling and five-axis cutting tool path planning of radial-flow integrated impeller
Abstract：Radial-flow integrated impeller, which are mass-produced because of the wide use in turbomachinery, such as steam turbine and hydraulic turbine. As a kind of essential power components, radial-flow integrated impeller is one of critical parts of basic industry and energy industry. Design and manufacturing techniques of radial-flow integrated impeller are researched all the time in modern manufacture industry. Radial-flow integrated impeller have a extremely complex surface. Its blade are smooth, thin, and highly twisty, difficult to machining. High surface quality are also requested. Nowadays, traditional machining method cannot satisfied the request of machining quality prefect any longer. This paper presented a new method of three-dimensional modeling and machining simulation of radial-flow integrated impeller, which based on UG. FIDIA HS664RT five-axis numerical control machining center will be the equipment of machining. First step, build parametric modeling in CAD module in UG. Then finish the machining simulation in CAM module in UG and create cutter path. Finally, post-process will be accomplished after machining simulation in order to create machining program used in practical machining.
