Abstract Due to the coupling effects of various technical process factors on numerical control (NC) machining, varying degrees of NC machining distortion is almost inevitable for most aeronautical monolithic components. This brought critical negative effects on guaranteeing product accuracy, improving machining efficiency and reducing manufacturing cost. The NC machining distortion of aeronautical monolithic component is one of most severe challenges in aviation manufacturing industry. This paper summarizes and analyzes the factors, internal mechanism and prediction technology of NC machining distortion of aeronautical monolithic components. Furthermore, the research progresses of distortion control and distorted components correction technologies were expounded. Finally, prospects for the development trends of distortion prediction and control technologies of aeronautical monolithic components is presented.
