CAD/CAM for Shrouded Blisk by Electro-Discharge Machining

Li Gang1,Wang Zhenlong1,Zhao Wansheng2,Wu Xiang1(1.School of Mechanical and Electrical Engineering,Harbin Institute of Technology,Harbin,150001,China;2.School of Mechanical Engineering,Shanghai Jiao Tong University,Shanghai,200030,China)  
To produce shrouded turbine blisk by electro-discharge machining(EDM),a special CAD/CAM system called the BliskCad/Cam is developed to solve the problems,such as electrode designing and manufacturing,searching path for multi-axis NC-EDM,and precision measurement and detection,etc.BliskCad/Cam can perform parametrical reconstruction of 3-D model of the blisk,intelligent design of complex shape electrode,automatical generation of NC codes for electrode manufacturing,searching of interference-free tool path for multi-axis NC-EDM and machining simulation,etc.An experiment on the shrouded blisk of a certain aeroengine proves that BliskCad/Cam meets the requirements of high precision machining,and also reduces 50% of the accessorial time.
