The analysis explored the impact of cutting parameters on the tool wear process. It shows that the cutting parameters affected the tool-wear stages. Under high cutting parameters, the tool bypasses the normal wear stage and transitions directly to the rapid wear phase. The rake face exhibits cratering and fine chipping, whereas the flank face displays normal wear bands and groove wear. The wear mechanisms of the CBN tools when cutting Vit1 include abrasive, diffusion, oxidation, and adhesive wear. These types of wear are caused by several mechanisms.

Experimental results indicate the brazed diamond wire with tungsten core was found to produce higher slicing efficiency, lower sawing force, smaller wire bow angle, and better wear resistance, in comparison to the electroplated diamond wire (EWD). Almost no diamond grain fell off from the brazed diamond wire after slicing, which was attributed to the strong interfacial chemical bonding between diamond grains and brazed alloys. Exposed and sharper grains enhanced the efficiency of brazed diamond wire but produced a rougher surface than nickel-coated electroplated diamond wire.

The influence of different grain growth inhibitors on the kinetics of WC coarsening in WC-10 wt% Co cemented carbides was investigated. The presence of complexions having a thickness of nearly 1 to 3 nm at WC/Co interfaces was established by STEM, EDX and HRTEM as a result of adding VC, Cr<sub>3</sub>C<sub>2</sub> and TaC to WC + Co. WC grains in WC-Co cemented carbides containing Mo<sub>2</sub>C was characterized by the presence of near-surface layers of (W,Mo)C having a thickness of about 100 nm and absence of complexions at the WC/binder interface. The values of activation energies for all the GGIs except for Mo<sub>2</sub>C lie in the range typical for the solid-state diffusion-controlled processes, therefore, the solid-state diffusion of W and C atoms through the nm-thick complexions is presumably a limiting stage of WC coarsening. Considering the activation energy and distribution of heavy elements in the binder for the samples doped with Mo<sub>2</sub>C, one can assume that in the liquid binder containing dissolved W, C and Mo atoms, molybdenum suppresses the diffusion of tungsten atoms.
