The invention provides an automatic rotating angle control method for a cutting bed and a cutting shear. The method comprises the following steps in sequence: setting the minimum target angle value of the rotating angle to be a rated angle Alpha (Alpha is more than 0) in the condition that the cutting shear is not lifted; directly rotating to cut without lifting the cutting shear if the rotating angle Beta (Beta) is more than 0) is more than the rated angle Alpha when the cutting shear needs to have a rotating angle; rotating the cutting shear by Alpha/2 angle if the rotating angle Beta (Beta is more than 0) is less than the rated angle Alpha, wherein the angle Gamma=Beta + Alpha/2 is more than Alpha; adopting the rotating angle for rotating to cut without the cutting shear; rotating the cutting shear at Alpha/4 angle again if the angle Gamma is less than the rated angle Alpha; and then directly adopting the rotating angle for rotating to cut without holding the cutting shear. By adopting the method, the cutt
