摘要
航空航天整体结构件加工变形问题制约着其应用的广度和深度,在加工中或者针对成品进行校形处理是提高整体结构件形状精度的有效手段。本文在分析整体结构件产生加工变形原因的基础上,重点讨论了电磁校形、激光校形、超声波喷丸校形、蠕变时效校形、振动时效校形这几种新型校形技术及其研究现状。
The machining deformation of aerospace monolithic component restricts the extent of its application. Increasing correction process during manufacturing or for the finished products is an effective means to improve the shape precision of the monolithic component. In this paper, the reasons for the machining deformation of components are expounded, the new types of correction technology such as electromagnetic correction, laser correction, ultrasonic shot peening correction, creep aging correction, vibration aging correction and its research status are discussed.
