Abstract

According to the difficulty of cutting the ZTC4 material, slot cutting experiments were designed and three directional dynamic milling force were obtained. Instantaneous milling force model and multiple linear regression was used to analyze three directional milling force coefficients and edge milling force coefficients. To evaluate the performance of the dynamic milling force model, a new slot cutting experiment was designed. The comparison of simulations and experiments indicates the average milling force error are 5.74%, 3.93%, 7.98%, the dynamic milling force prediction model fits well in cycle, trend and amplitude. The feasibility and accuracy of the model for predicting the instantaneous milling force is verified.
