Investigation on wear characteristics of cemented carbide tools in finish turning spherical shells of pure iron

A thin-walled spherical shell made of pure iron material is a key part precision physical experiments. Tool wear characteristics freeform surface parts are significantly different from those single-point turning due to the movement contact point between tool and workpiece, which affects form accuracy integrity workpiece. However, there lack comprehensive understanding in machining materials. Therefore, we proposed mathematical model investigate cemented carbide further when The results show that uniform flank land notable notch occur end face, but disappears only exists shell. Based on major position minor position, developed explain formation mechanisms during Theoretical experimental movement. Spherical face have same mechanisms, mainly composed adhesive wear, diffusion oxidation wear.
