Experimental Research to Determine the Optimal Cutting Parameters for Reducing Roughness in Turning of C45 Steel

This study employed the Taguchi method to optimize cutting parameters for minimizing surface roughness during turning of C45 steel. The cutting speed, feed rate, and depth of cut were chosen as input factors and assessed at three levels: Low, medium, and high. An analysis based on Taguchi method was conducted to examine the impact of each input factor on surface roughness. The findings revealed that the feed rate exerted the greatest influence on surface roughness, followed by cutting speed and depth of cut.
