Abstract

Fixtures have an important influence on the machining process of thin-walled parts (TWP) and directly determine their final quality. Aiming at the problem of machining deformation caused by weak rigidity of TWP, an ice-based fixturing (IBF) is designed by taking advantage of the rigidity and viscosity of ice. The feasibility of IBF is then demonstrated based on the published papers of the authors of this paper. Afterwards, the structure and refrigeration process of IBF are described in detail, and the refrigeration capacity of the IBF system is analyzed, and the experimental results show that the IBF can achieve uniform and reliable icing. Finally, the process steps are formulated. This paper can provide a valuable reference for the development of advanced fixtures.
