Abstract
The selection of milling tools for SiC14Cu4Mg0.5Si based on Aluminium matrix 2A14 was analyzed, and the factors that affect the efficiency of the milling were discussed. The SiC14Cu4Mg0.5Si was designed for use on the moon landing vehicle or missile wings, but the hardness of aluminium-silicon carbide composite material was very high, much higher than the general hardness of cemented carbide, which will bring many difficulties in the aluminium-silicon carbide composite material processing. The chemical compositions of SiC14Cu4Mg0.5Si were analyzed. A new selected indexable cutter was designed to mill SiC14Cu4Mg0.5Si. The structure design of milling cutter was different from the conventional milling cutter, breaking the previous limitations to a certain extent, pioneering the idea. The tool material wear was detected by experiments. The mechanical and physical properties of SiC14Cu4Mg0.5Si were also tested. SiC14Cu4Mg0.5Si exhibited different surface quality characteristics under different milling tools.
