Notes:
Cutting tests had been done on the Austempered Ductile Iron (ADI) with ceramic cuttingtools. The wear shape of the cutting tool’s surface was observed by the Scanning ElectronMicroscope (SEM). The micro-wear area of the tools was analyzed with energy spectrum. Study onwear shape and wear mechanisms were done when infeed cutting ADI. The result shows that: thecutting speed is an important factor to the tool wear when infeed cutting ADI with CC650 tool, andwith the increase of the cutting speed, the wear value of cutting tool increases obviously. The flankof cutting tool (CC650) has wear land of definite width during cutting, and shows obvious abrasivewear. The crate wear shape of rake face is almost joined to major cutting edge, it is different fromthe typical crate shape of rake face. Elements Fe, Si and Mg in ADI material diffuses to the surfaceof cutting tools (CC650) after cutting, the diffusion exacerbates the wear of cutting tools, and thediffusion degree of rake face is larger than that of flank, abrasive wear, adhesive wear and diffusivewear is chief reasons for tools wear
