The method is limited by the existing precision forging technology, the tip part of the blade cannot be precisely forged and formed, and numerical control machining is needed. Therefore, blade tip machining puts high demands on the fixture. The blade tip machining clamp requires uniform clamping force, not only avoids deformation of a blade profile caused by overlarge clamping force, but also accurately controls the clamping force to avoid the phenomenon that the blade moves due to cutting force when the blade tip is milled, so that the machining precision of the blade is influenced. In order to meet the requirements, a special fixture is required to be designed to complete the processing of the blade tip.
