摘要：

Polycrystalline diamond (PCD) tools have been obtained increasing application in aluminum alloy processing industry due to the excellent surface finish and tool life comparing with other traditional tools. Investigation of the wear mechanism of PCD milling tool for machining Al-Si alloy at cutting speed of 5000m/min (n=12732r/min) has been performed. The wear morphology of tool has been studied by scanning electron microscopy (SEM) and energy dispersive spectrometer (EDS). Results show that PCD milling tool suffers from abrasive wear and diffusion wear on the flank face and adhesive wear on the rake face in the machining process.
