Method for manufacturing of a secondary flow channel |
摘要 |
In a process to manufacture a turbine blade or vane, slits if pre-determined size, position and shape are cut into the metal by presentation to a first surface of a first form electrode (A), followed by presentation of a second form electrode (B) to the second surface. The slit is cut by electrochemical erosion and subsequently finished by polishing with abrasive particles. |
