Inducer is a fluid device with new structure and high performance. With excellent cavitation resistance, it is a critical component of the turbine pump of liquid-propellant rocket engine.It introduces the structure, function and assortment of inducer, the function and characteristics of the UG software, and the design methods and core elements of the inducer cutter locus in a certain type of aero-engine. It has been verified that by using the procedure and cutter locus, processing inducer can be completed with higher efficiency. Meanwhile, the problem of undercutting in hub ,finishing can be solved by adjusting the tangential and the radial extension parameters. It also summarizes the network communication and the tool parameter setting of the five-axis machining center of the same type. Finally it puts forward the key points and the problems to be solved for the future research on this type of components.
