Article Preview

This work explored the process of safety decline based on stress field and deformation analysis of cutter, founded vibration models of centrifugal force and cutting force, and investigated the effect of dynamic balance precision and natural frequency on safety and stability of cutter. Using the model of maximal residue height on machining surface based on the vibration of cutter and experiment results, characterized safety decline behavior of high speed milling cutter. Experiment results verified that safety decline caused by the vibration of centrifugal force was much higher than the vibration of cutting force. The results indicate that the deformation of cutter and relative displacement of subassembly change mass distribution of cutter with rotational speed increasing in unimpaired state of cutter’s integrity, direct results are dynamic balance precision decline, the safety and stability state of cutter gradual deterioration because of the vibration, the safety of cutter occurs a dynamic decline in high speed milling.
