摘要
航空整体结构件数控加工过程中受多种因素的耦合作用,导致其加工后产生不同程度的变形,对产品的精度保障、加工效率的提升与制造成本的控制产生严重的不利影响。航空整体结构件数控加工变形是航空制造业面临的严峻挑战之一。首先对航空整体结构件数控加工变形的影响因素、内在机制和变形预测技术进行综述分析,进而阐述航空整体结构件数控加工变形控制及变形校正技术的研究现状,最后对航空整体结构件加工变形预测与变形控制技术的发展趋势进行了展望。
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.
