This paper deals with the effect of minimal quantity lubrication (MQL) on tool life (flank wear). crater wear of various coated high-speed steel tools and finished surface roughness in hobbing. Experiments were conducted by simulation hobbing by fly tool cutting on a milling machine. The results are summarized as follows. https://www.bekindtopets.com/quick-buy-Titans-Pets-First-Reversible-Dog-Bandana-deal-zone/
