Analytical Study of the Effect of Tool Texture on Lubrication Performance in Turning Process

Wear, friction and lubricant are important issues in all disciplines, including in turning. Normally, lubricant is used to reduce the temperature of the tool and also to reduce the friction between the part and the tool. So far, many studies have been done on lubricant optimization by changing its structure, for example by adding nanoparticles to the lubricant. In this article, with a new approach, the effect of creating a surface pattern on the accuracy of the lathe has been studied. More precisely, the effect of holes created by laser engraving on the friction behavior and the formation of the fluid layer in different states were investigated by numerical analysis. In general, the amount of load as well as the speed of chipping is an influencing parameter on the amount of friction. Here, by keeping these two parameters constant, the effect of the number, depth and size of the surface pattern was investigated.
