Embodiment Construction
[0066] Theoretical basis;
[0067] a. During the milling process of the blades and flow channels of the compressor impeller, the excess material is forcibly removed from the part body by milling the part with the milling cutter, so that the material stress will be lost after milling, and at the same time due to the milling force, clamping force, etc. Therefore, no matter how to adjust the milling parameters, change the milling force and clamping method, etc., the deformation of the meridian surface cannot be completely eliminated, and the accuracy requirements of the meridian surface of the part cannot be met.
[0068] b. Change the machining plan, redistribute the machining allowances, change the final machining of the atomic meridian surface to semi-finishing machining, and leave enough finishing allowances. After milling, the stress of the material is released, and the strain and deformation of the parts are all eliminated. After that, the final machining (finishing) of the...
