Inconel 718 is wildly used and catalogued as one of the different-to-cut materials in aerospace industry. Recently several papers reported that micro-texture fabricated on a tool insert is able to improve the mechanical and thermal conditions at the insert faces. The purpose of this paper is to investigate the effect of micro-texture at the insert flank face on the evolution of flank wear in turning of Inconel 718 under different coolant supply methods. Four patterns of micro-texture were fabricated on the flank face of the coated cemented carbide insert at three levels of texture depth. After the finish-cutting experiments and measurements, it was found that micro-texture consisting of 10 m-deep microgrooves vertical to the cutting edge enhanced the cutting performance and exhibited the longest tool life.
