Abstract

Aluminum alloy is applied in aerospace widely and prominently due to its advantages in physical and mechanical properties. The clamp method for thin-walled aluminum alloy workpiece remains an important challenge in processing field. This paper presents an optimized clamp method for thin-walled aluminum alloy rotational conical with large diameter during processing to ensure the wall thickness of the parts in various regions. Based on ANSYS, the vibration modal analysis model and the simplified cutting model are established respectively, for studying the modality and machining distortion. The influences of three clamping conditions on the most sensitive area of parts are compared. Base on the simulation analysis, the verified machining experiments of three different clamp methods are conducted. As the study subjects, the dimensional precision of wall thickness and the weight of parts are analyzed. The results show that the optimized contour support clamping condition can effectively guarantee the quality and precision of parts’ processing.
