Abstract :This study examines the effects of spindle speed, feed rate, and depth of cut on machining performance during mild steel machining. Experiments were conducted with spindle speeds ranging from 105-225 rpm, feed rates of 0.10-0.34 mm/rev, and depths of cut between 1.0-3.4 mm. Results showed that increasing these parameters improved the material removal rate (MRR), with the highest MRR reaching 261.30 mm³/min. However, tool wear rate also rose proportionally, peaking at 7.65 mm³/min, highlighting a trade-off between productivity and tool durability. Machining time decreased with higher spindle speeds, with the shortest time recorded at 1.35 minutes. Statistical analysis using paired sample t-tests and correlation coefficients revealed strong positive correlations between spindle speed and MRR (r=0.973), spindle speed and tool wear rate (r=0.994), and a strong negative correlation between spindle speed and machining time (r=-0.935). These findings highlight the importance of optimizing cutting parameters to balance productivity, tool wear, and efficiency. The study provides practical insights for industrial machining of mild steel and recommends future exploration into advanced cooling methods and tool materials to enhance machining performance under similar conditions, contributing to improved precision and resource efficiency.
