Dynamic Analysis of Milling and Burr Morphology in 6061 Aluminum Alloy

Abstract

6061 aluminum alloy is a common aluminum alloy material with good machinability and mechanical properties, which has been widely used in high-end manufacturing fields such as aerospace; Thin wall features are particularly common in the machining process of parts. This article uses a universal tool milling force mechanical model to model the dynamics of the machining process. Firstly, the cutting process is analyzed mechanically, and then the cutting force coefficient is identified through cutting experiments to obtain the milling dynamics model. The calculation results of the model are compared with the cutting experiment results, verifying the effectiveness of the model. The morphology of fine burrs in the machining process of parts was analyzed, and the relationship between machining parameters and burr morphology characteristics was experimentally studied, providing a certain reference for suppressing the formation of fine burrs in the machining of thin-walled aluminum alloy parts.
