Wear and Breakage Features of Multi-Coated Tools in Turning Hardened Steel
The wear and breakage features of TP1000 multi-coated tool were investigated through a series of cutting experiments. These experiments were performed for turning hardened 45 and T10A steel by orthogonal experimental method. SEM and XRD analysis were conducted on cutting tools. The results show that both wear and breakage occur when turning hardened 45 steel. The major wear mechanism is abrasion and oxidation, and the major breakage mechanism is surface spall. When turning hardened T10A steel, the main disability is breakage, and the major breakage mechanism include surface crack, spall and tipping.
