Numerical Simulation of Whole Impeller for 5-Axis Machining Based on UG

The manufacturing template of whole impeller 5-axis machining based on UG was re-developed with NURBS interpolation principle and UG/knowledge fusion technology, and 5-axis NC machine and part model were established, each parts of machine were simulated in 3D motion with reading NC code. Human-computer interaction was processed fast with the template and guiding of digitized manufacturing, the cutting tracks of half-finishing machining and finishing machining for whole impeller were produced fast. The template involves 3-D modeling, craft flow programming of NC machining, program of NC machining and etc. and is tested on 5-axis NC machine, it is indicated that the scheme and program of NC machining for whole impeller is feasible.
