Abstract :This study presents a comprehensive statistical analysis of the effects of drilling parameters on cutting forces and hole quality in AISI 1050 steel, utilizing Analysis of Variance (ANOVA) to evaluate the significance of various factors. The research employs a full factorial experimental design to systematically investigate the influence of drill geometry, cutting speed, and feed rate on thrust force, torque, and several metrics of hole quality. The ANOVA results indicate that drill geometry is the predominant factor, accounting for a significant portion of the variance in thrust force and torque, with statistically significant F-values, thereby confirming its critical role in drilling performance optimization. Moreover, cutting speed and feed rate also demonstrate substantial contributions to the variance in cutting forces and hole quality metrics. These findings highlight the importance of these parameters in enhancing drilling efficiency and minimizing defects such as burr formation and surface roughness. The interaction between these parameters is essential for achieving optimal drilling conditions, as evidenced by the statistical modeling approaches employed in the study. In addition to ANOVA, the study incorporates Taguchi method\\\'s signal-to-noise ratio analysis to further validate the findings. This method underscores the superior performance of specific drill geometries in minimizing variability in drilling outcomes, thereby reinforcing the significance of drill design in achieving high-quality holes. The insights derived from this research provide a robust foundation for optimizing drilling processes in industrial applications, particularly for medium-carbon steels like AISI 1050, and offer valuable guidance for future research endeavors aimed at enhancing machining efficiency and quality. The implications of this study extend to practical applications in manufacturing, where understanding the interplay of drilling parameters can lead to improved operational efficiencies and product quality. The findings contribute to the existing body of knowledge by elucidating the critical factors influencing drilling performance, thus serving as a reference point for further investigations in the field of machining and materials processing.
