A study on the economics of hypereutectic Al-Si alloy cutting with single crystal diamond tool

단결정 다이아몬드 절삭에 의한 과공정 Al-Si합금의 경제성에 관한 연구

A hypereutectic Aluminum-Silicon Alloy is widely used in the parts of automobile because of high-resistance and good strength. In this study, the cutting of hypereutectic A1-Si alloy for economical production was investigated by simulation. Tool life and the extraction rate of Si particles is inversely proportional to the depth of cut. When decreasing the depth of cut, the reduction of single crystal diamond tool cost and tool change time is achieved.
