Abstract
- Thin-walled parts are critical structural components in the aircraft industry. However, because thin-walled parts have low stiffness, it is impossible to eliminate the elastic deformation generated by cutting force during the machining process, resulting in poor machining accuracy. In this paper, the simulation and surface roughness prediction model of thin-walled necks with ribbed constrained at both ends were constructed to understand the deformation mechanism and processing quality of thin-walled necks. The deformation mechanism of thin-walled necks with thin rib structures was revealed, and the deformation mode of the "S" shape to the "V" shape of fine boring thin-walled parts was analyzed. Then, the temperature field and the residual stress of the thin-walled neck with the spindle speed, feed, and depth of cut were revealed. Finally, the surface roughness prediction model for thin-walled parts is established using multiple regression functions. This study provides a theoretical foundation and technical assistance for managing the boring quality of thin-walled items by deeply understanding the machining deformation and cutting process mechanism.
