Abstract

In five-axis flank milling, the continuous change of the tool posture complicates predictions of the instantaneous undeformed cutting thickness (IUCT). The milling force prediction accuracy is improved in this study using a micro-element milling force model for the an IUCT method for a flat-end milling cutter with the IUCT divided into two parts. The results show that the milling force model calculational efficiency is improved by 40% compared to a previous model. The model predictions were then verified against flank milling tests. These results show that the model is accurate and efficient.

Key words
