Abstract Nanosecond surface dielectric barrier discharges (ns-SDBDs) are a class of plasma actuators that utilize high-voltage pulse nanosecond duration between two surface-mounted electrodes to create an electrical breakdown air, along with rapid heating. These usually produce multiple filaments when operated at high frequencies, and the heating leads formation shock waves complex flow fields....

Recently, the requirements for machining shape-complex products made of hard-to-machine materials, including carbide, have been increasing significantly. However, their is rather problematic. Additionally, a high-quality standard machined surface generally required, not only in terms roughness but also geometric accuracy surface. All this while maintaining high level economy process. meeting th...
