【Abstract】 The technology of designing the stock of blade forgings is the key in forge work. So there are many differences between turbine blade and other parts in this technology. According to the special geometric structure of turbine blade and the forging procedures, this article analyzed some factors which influencing allowance for machining, then discussed how to add the allowance to different parts of blade through expanding and extending the profile of blade, finally confirmed the allowance magnitude of different parts.更多还原
