2020/9/2Relevant cutting experiments showed that the established 3D model accurately predicted the material removal, chip morphology, machined surface finish, and cutting forces. It was found that the matrix-particle-tool interactions led to particle fractures, mainly in the primary shear and secondary deformation zones along the cutting path and beneath the machined surface.

The approach is to use an analytical cutting model to map the measurable out-puts of cutting experiments to material deformation characteristics. The method is validated with simulations. Additionally, a new material model is investigated for modeling work material thermal softening damping behavior that was observed during the state-of-the-art method.

Nowadays, high-speed cutting of difficult-to-machine metallic materials gets more important in industry to reduce manufacturing times and hence production costs. On the other hand, increased cutting speed is one of the most important factors influencing tool life, as it enhances built-up edge formation, oxidation of the tool#39;s surface and tool wear.
