<![CDATA[General Background: Conventional lathe turning processes remain widely utilized across manufacturing industries and educational workshops due to their operational simplicity and flexibility. Specific Background: The quality of turned components heavily depends on the condition of the cutting tools used, where tool wear during cutting operations reduces workpiece surface quality. Knowledge Gap: Existing practices often lack comprehensive quantification regarding how varying spindle speeds and feed rates accelerate mass loss and surface degradation in conventional setups. Aims: This study aims to analyze the effect of high-speed steel tool wear on surface roughness during conventional lathe operations using varying spindle speeds and constant feed rates. Results: The findings indicate that tool wear increases proportionally with higher spindle speeds and larger feed rates, directly resulting in higher workpiece surface roughness. Novelty: This research provides an accessible evaluation of mass-loss tool wear utilizing two distinct feed rates across multiple spindle speeds without requiring microscopic equipment. Implications: Monitoring tool wear and optimizing cutting parameters are vital for maintaining machining precision and industrial productivity. Key Findings Highlights Tool wear values increase significantly alongside higher spindle speeds due to elevated cutting temperatures and friction. Larger feed rates induce greater cutting forces, leading to accelerated tool wear compared to smaller feed rates. Advanced tool wear directly diminishes cutting stability, producing rougher workpiece surfaces. Keywords Conventional Lathe, Tool, Tool Wear, Hss Tool, Turning Process]]>
