Abstract: The appearance and development of biomimetics in tribology brings a new research direction for antifriction technology of tool. The orthogonal experiments of the cutting performance of micro-textured cutting tool in machining titanium alloy was presented. Micro-grooves were made using laser on the rake face of uncoated tungsten carbide cutting inserts. Minimal quantity lubricant (MQL) and cryogenic minimal quantity lubricant (CMQL) were used. Three cutting force components were measured and compared. Tool-chip contact length and worn surfaces were examined using scanning electron microscopy (SEM). It was found that under the lubricated condition the surface micro-grooves could effectively improve the friction status between the tool and chip, thereby reducing cutting force and cutting temperature. The surface micro-grooves could also improve the adhesion of titanium alloy. Without lubricant, micro-grooves still had a certain "lubrication" effect.
