Abstract
Integral production technology of impulse turbine runner effectively prevents phenomenon of bailer broken when generation unit working, and then improving its service life. Based on comprehensive application of vibration inhibition technology and machining optimization path CAD/CAM technology, the high-speed plunge milling process is forwarded in this paper under the condition of big slenderness ratio and be able to present processing vibration. By using matching principle of tool connection point surface smoothing processes and the helix curved surface processing method this process successfully solves the problem of interfering point state complex in finishing plunge milling impulse water turbine whole runner and it achieves high active finish machining by three-axis NC process. This technology has also successfully been used in the power station whole runner manufacturing process in HPE group.
