doi:10.3901/JME.2016.05.202

Abstract

Abstract: Cutter is under the action of intermittent cutting load in high speed milling, the energy keeps cumulating in the interior of cutter and causes irreversible movement of atomic and the change of macrostructure. Safety of high speed milling cutter presents trans-scale correlation characteristics. In order to improve the safety of cutter, a trans-scale design method on safety of high speed milling cutter is proposed. Trans-scale correlation is achieved by using the method of force connection between continuum mechanics and molecular dynamics. Based on the entropy evaluation method, mesoscopic safety of cutter is quantified. Safety entropy model is proposed, and the model is used to explore relationship between macro and mesoscopic structures of cutter. The response characteristic of cutter safety to its design parameters is revealed, the parameters are diameter, number of teeth, tooth root structure, installation rake angle and configuration parameters of atomic group. The trans-scale correlation design model of high speed milling cutter safety is established by using axiomatic design method, the safety of cutter is verified. The results of analysis and experiment show that the irreversible movement of atomic with different features and degrees occurs separately in high and low entropy area. Tooth root structure and installation rake angle that can have a significant effect on atomic configuration. The safety of cutter is improved by using trans-scale design method, and the high efficiency, reliable and stable manufacturing is guaranteed.

Key words: axiomatic design, entropy, high speed milling cutter, safety, trans-scale correlation
