Abstract
- Due to the low rigidity, the milling process of cantilever thin-walled structure (CTWS) inevitably generates machining-induced deformation, ultimately resulting in poor surface quality and thickness accuracy. In this paper, to avoid these issues, a novel and green ice-based fixture (IBF) is innovatively proposed to hold CTWS firmly to suppress machining deformation during the whole processing. Firstly, a stair-step model is established to express machining-induced deformation of CTWS with/without IBF. Next, IBF is designed to clamp CTWS steadily. Secondly, finite element model (FEM) for CTWS is utilized to simulate milling deformation with/without IBF to reflect the effect of IBF on eliminating CTWS deformation. Finally, the experiment of CTWS milling is carried out, and the experiment results show that IBF can achieve a reliable and stable holding for CTWS, and hence suppress machining-induced deformation and improve thickness accuracy. In this paper, research on IBF for CTWS processing provides reference and guidance for the application and promotion of IBF in industry. [ABSTRACT FROM AUTHOR]
