Abstract: |
The machining process of the closed impeller used in a petrochemical industry with a nickel-based superalloy was analyzed. The processing method of multi-axis CNC EDM was put forward. The design and machining process for the complex forming electrode was introduced and a high efficient machining process was given. AFM technology of the passageway of closed impeller was introduced also. |
