The existing technologies of production of compressor blade butts related with traditional machining methods, including broaching and milling. Application of these machining methods requires further superfinishing operations to ensure the required quality of compressor blades. The automated highly-productive grinding of blade butts is an effective method to improve performance and quality of blade production. The technologies of profile and contour grinding of blades of a rotor and a compressor stator provide an automated machining of the outer parts contour in the same coordinate system, implement machining based on 3-D models of theoretical blade surfaces, ensure the required quality parameters of the part surface layer without additional finishing operations.
