Due to the wide applications of aluminum alloy in numerous industrial sectors and products, significant attention has been paid by many researchers to improve the production and manufacturing aspects of aluminium alloys and related products. One of the main concerns in this regard is the cutting tool life when machining aluminium alloys. This work aims to present the capability and performance of a new strategy of life improvement in the tungsten carbide inserts by creating micro-textured grooves on their surface. For this purpose, the laser was used to create the different morphologies of textures on the insert surfaces. The grooves were created with different distances in parallel to the cutting edge on the tool rake face. The effects of fabricated grooves on the tool wear attributes were discussed in three directions, including the main edge (x-direction), side edge (y-direction), and radial (in the direction of 45 degrees) and the effect of these grooves/textures on the surface roughness attributes were also studied. To that end, experimental works were performed under dry and minimum quantity lubrication (MQL), as well as three levels of cutting speed, feed rate, and grooves distance. The experimental results were compared with those measured under non-textured inserts. Finally, the obtained results were statistically analyzed, and the empirical models were formulated. Experimental results indicated that micro-textured inserts in both MQL and dry conditions led to surface quality and tool wear as compared to readings made under non-textured inserts.
