Description

technical field

[0001] The invention relates to a mechanical processing method and special tooling, in particular to a processing method and special tooling for blade-shaped workpieces of turbine machinery. Background technique

[0002] Blade-shaped workpiece is one of the extremely important parts of turbine machinery, which is characterized by complex shape, high technical requirements and difficult processing. There are many types of blades, but all kinds of blades are composed of three parts: blade top, blade body (air passage part) and blade root (assembly part), and the blade body part includes an inner arc and an outer arc. The current processing method is to process a single rough blank one by one. Due to the complex shape of the blade-shaped workpiece, there are many surfaces to be processed, including multiple planes with the blade top and blade root, as well as the inner arc and outer arc of the blade body. The two arc surfaces of the arc need to be processed one...
