The Impeller Five-Axis NC Machining Simulation Based on UG NX 7.5

To improve the processing efficiency and Surface qualityof impeller. Impeller processing difficulties as a major object of study were researched by this paper. Using UG7.5 impeller processing module, Based on the impeller feature division idea and to optimize the impeller machining path.Finally, Through it carried out the tool path generation and simulation and verify the feasibility of processing. To effectively enhance programming efficiency and processing quality.
