Zr-based bulk metallic glass is an amorphous alloy. In order to study the burr problem in the groove milling process of Zr-based bulk metallic glass, the milling force in the process is studied experimentally. Then the effect of milling parameters on the burr of Zr-based bulk metallic glass was studied, and the relationship between milling force and burr was analyzed. In order to further study the milling burr of amorphous alloy, under the same test parameters, the single crystal alloy material (nickel base single crystal superalloy DD5) and the traditional polycrystalline metal material (304 stainless steel) were selected for comparative test and analysis. The results show that Zr-based bulk metallic glass has good groove milling machinability. The test results provide some experimental basis for groove milling of Zr-based bulk metallic glass.

The milling groove experiments of Zr-based bulk metallic glass (Zr-based BMG) (Zr52Cu17.5Ti16Ni12Nb2.5) are conducted by using an ultra-precision lathe. In order to study the milling groove flank contour accuracy in mesoscale groove milling for Zr-based bulk metallic glass component, the milling force and the flank contour shape were investigated by single-factor experiment. The effect of milling process parameters of Zr-based bulk metallic glass materials on the milling force and the flank contour profile of milling groove were obtained, and the relationship between flank contour profile of milling groove and milling force was also obtained. The flank contour profile of milling groove for Zr-based bulk metallic glass is analyzed theoretically. The effect of milling experimental parameters on the deviation between the actual flank contour profile of milling groove and the theoretical flank contour profile of milling groove is analyzed and summarized through the experiment.
