Experimental Study of Tool Texture on Machining Forces in Hard Steel Turning Process

In this article, the effect of creating a surface pattern on the expression of cutting has been studied. More precisely, the effect of the texture created by laser engraving on the values of machining forces was investigated in different states, and these tests were performed both in the presence of lubricant and in its absence. The parameters of depth, pitch, texture diameter and distance from Cutting edges were considered as tool texture parameters. A total of 9 experiments were conducted using the Taguchi test design method. Lubrication in both textured and non-textured tools reduced the machining force by 30-35%. In the end, the machining forces obtained from the test were compared with textured and non-textured tools in the presence of lubricant, and it was observed that due to texturing of the tool, the machining force decreased by about 28%.
