[0018] Such as figure 1 As shown, a four-axis milling machine processing method for a steam turbine blade is shown. The steam turbine blade structure includes four parts: inner arc, back arc, steam outlet edge and steam inlet edge, and the steam turbine blade processing technology is processed in the following steps:
[0019] Step (1): Clamp the blank to the flat-nose pliers of the general milling machine, and use the end mill clamped by the port of the general milling machine to process the blade root end face and the blade crown end face through rough milling and finishing milling;
[0020] Step (2): Clamp the processed blank to the three-center fixture on the four-axis milling machine, and use the ball-end knife installed at the port of the four-axis milling machine to process the blade root end face, middle boss and blade crown end face in sections. It is required that the transfer volume of leaf root and leaf crown is 3mm, the volume of inner and back arc single side is 2.55mm...
