Abstract
In order to reveal the wear mechanism of diamond tool in precision cutting large-aperture aluminum alloy mirror, molecular dynamics simulation is carried out in this work. The simulation results indicate that diffusion wear is the dominant way of the tool wear, which is in consistent with the cutting experiment. EDS of the aluminum alloy chips shows that Cu elements result in the phenomenon of chemical wear for diamond tool in the precision cutting process. Therefore, the wear mechanism of diamond tool in precision cutting large-aperture aluminum alloy mirror is a combination of diffusion wear and chemical wear. In addition, through the micro topography of the diamond tool wear zone, it can be found that the flank wear is the dominant form of the cutting tool. The results of the orthogonal experiment show that the influence of the tool clearance and feed rate on tool wear is greater than that of the cutting speed and tool arc radius. The results of single-factor experiment indicate that with the increase of the feed rate, the tool wear increases. While with the increase of the tool clearance, the tool wear decreases.
