“…It can be seen that the exponent of cutting force ratio nf is approximately proportional to the cutting speed, and the inclination as obtained by a least-squares method is 7.938×10 -4 . 4) yields the same results as the face cutting of single crystal silicon that we have performed, and it is considered that the main cause of tool wear is due to silicon particles [18].…”

During of hypereutectic Al-Si alloys, tool wear increases owing to the presence of silicon particles. Therefore, polycrystalline diamond tools are typically used, but they are very expensive. The purpose of this study is to examine the tool wear characteristics during the end milling of hypereutectic Al-Si alloy (A390-T6) by using comparatively inexpensive diamond-like carbon coated cemented carbide tools. Al-Si alloy was end-milled by changing the cutting speed. Our results revealed that the width of flank wear land increased monotonously with increasing of the cutting force regardless of the cutting speed. In addition, the experimental equation of the width of flank wear land was derived as a function of cutting speed and time, and it was clarified that width of flank wear land could be approximated.
