Abstract

Aimed at electro-discharge machining (EDM) of shrouded blisk, a special CAD/CAM system (BliskCad/Cam) was developed to implement 3-D parameterized automatic reconstruction of blisks, parameterized and intelligent design and machining of electrode, searching tool path for multi-axis NC-EDM, machining simulation and precision measurement and detection, etc. An experiment was conducted to test the performance of the special CAD/CAM system, and the sample blisk satisfies specifications of the blisk very well.
