| Abstract: | Electrochemical contour evolution machining(ECCEM) is promoted to machine integral turbine with big-twisted blades.The twisted blades dispersed data is processed.The multi-axis cooperative movement numerical programs are designed.The shaping law is analyzed.The cathode and the flowing field are designed properly.Key process issues,such as short circuit in exit and the blade back corrosion are discussed.The effective means are given for solving these problems.Machining test is carried out and the blades can satisfy precision demand.The integral turbine with big-twisted blades can be produced in batch. |
