Stability Analysis on Milling Processing of Aviation Aluminum Alloy

Abstract:

Based on milling experiment to explore the transformation and stress condition in the process of cutting of the thin-wall part made by aviation aluminum alloy, and then get data from the milling experiment through altering the axial cutting depth Ap=1 mm (a=1 mm), cutting radius Ae, spindle speed n and feed per tooth for milling force fz. Considering the milling force coefficient affected by each milling parameters, the orthogonal experiment of four factors and four levels are designed, and the milling coefficient is solved by MATLAB. The results indicates that the axial cutting depth Ap=1 mm (a=1 mm), the cutting force Fx increases with increasing in feedrate per tooth fz (c). the feedrate per tooth fz=0.03 mm (c=0.03 mm), the cutting force Fx increases with increasing in the axial cutting depth Ap. The discipline that the milling coefficient has an influence on milling force is obtained from the research which can provide the reference on the purpose of optimizing milling coefficient.
