Abstract:

For aircraft monolithic component, because of the complication of machining distortion, the straightening parameters are difficult to be determined exactly in the process of distortion correction, which may destroy the workpiece. The FEM analysis of the straightening process was executed based on the pressuredeflectionResidual deflection curve. According to this curve, the reasonable straightening parameter of pressure can be determined to apply to the straightening process and the safety load limit for the straightening process could also be determined by twice the slope of the elastic rebound curve to the load axis.

Key words: straightening, machining distortion, safety load limit, monolithic component
