Research on Multi-axis CNC Programming in Machining Large Hydraulic Turbine's blades Based on UG

Researched on the multi-axis CNC Integrated machining method of blade on large Francis turbine based on UG to automatic programming software architecture. Discussed the way to enhance the quality and to promote efficiency of machining. The key technology of five-axis CNC programming to large sculptured surface in hydro turbine's blade was introduced, which establishing 3-D model and tool-path generation and cutting simulation with small force, high precision and low cost. we have introduce this machining method and hope it is helpful to machining of similar parts.
