Abstract
Background: The patent of cutting operations is carried out with a cutting tool that is fed parallel to or at right angles to the work axis. The main objective of this study is to minimize surface roughness and MRR.
Objective: The effect of cutting parameters on surface roughness and material removal rate is investigated using AISI 1045 steel as a workpiece material, and single and double carbide cutting tools are used under dry machining conditions.
Methods: The cutting speed, feed rate, and depth of cut are considered input parameters for experimental purposes. Taguchi L9 orthogonal array design of experiments is used for designing the experiments. Parameters are optimized using Taguchi L9 orthogonal design of experiments and Analysis of Variance (ANOVA). MINITAB 17 software is used to solve the coefficients of the regression model.
Results: The result indicates that the cutting speed was the most significant influencing factor that affects the surface roughness, followed by feed rate and depth of cut for both single and doublecutting tools.
Conclusion: The minimum surface finish for the best cutting parameter was 0.95 μm for a single and 0.92 μm for a double-turning tool. The highest material removal rates for single and double turning were 6456 mm3/min and 6603 mm3/min. The result shows that while using double tools, the rate of material removal rate increased and the machining time decreased.
