- Abstract
The precision and efficiency of machining of aerospace thin-walled components (ATWCs) directly affect aircraft performance and reliability. This paper systematically reviews the cutting technology for ATWCs, covering advanced fixture technology, the prediction and control (or suppression) of machined surface integrity, deformation, and cutting chatter, as well as the application of digital twin (DT) technology. The section on advanced fixture technology provides a detailed analysis of the operational mode, structural features, functionality and applications of various advanced fixtures suitable for the machining of ATWCs. The surface integrity section discusses the mechanisms of surface state formation during machining of aerospace metal material parts, alongside predictions and control methods for surface integrity. The deformation section analyzes causes of machining-induced deformation in machining ATWCs and introduces relevant prediction and control methods. The cutting chatter section discussed the stability analysis techniques of cutting process and chatter suppression technology, including online monitoring and recognition, active and passive suppression technologies, and methods. The DT technology section showcases the specific application of this technology in the machining of ATWCs. The paper summarizes different aspects of these technologies, offering a comprehensive understanding and facilitating in-depth research into the machining technology of ATWCs. It can serve as a reference and guide for scholars conducting research in this field.
