Abstract
Chatter between the end mill and thin aircraft components reduces tool life and surface quality. This paper presents a time-domain chatter analysis that simulates the peripheral milling of thin aluminum plates. Peak forces and tool deformations were predicted in the time domain by simulation software written in C++. The maximum forces at various cutting depths and spindle speeds were predicted, and the stability lobe diagram was drawn in the frequency domain. The software was validated in comparison with the results of Professor Y. C. Shin’s experiments and was used to analyze the relationship between chatter and runout, number of teeth, and feed rate in virtual space. The chatter in transient state was simulated to predict the side effect of feed rate control.
