Introduction: Among alloys of medium-carbon and high-strength steel, EN 24 steel is characterised by its nickel-chromium-molybdenum composition. highly suitable for application in heavy-duty projects due to notable resilience damage, especially when exposed low temperatures. With the objective minimising surface irregularities, this research endeavours enhance milling process employing coated tungsten carbide (WC) tool inserts. Methods: Feed rate, cutting speed, depth cut, fluid are all crucial factors experimental investigation. Four distinct levels applied each factor. The utilises Design Experiments (DOE)-based Central Composite Response Surface Methodology. To predict output parameters, mathematical models developed utilising analysis variance (ANOVA) optimisation purposes. Results discussions: Through utilisation multi-objective optimisation, optimal combination inserts was determined, which provided irregularities 0.301 µm. Cutting speed (CS) 149.507 m/min, feed rate (FR) 340.27 mm/min, cut (DOC) 0.599 mm, (CF) 12.50 L/min parameters. morphologies machined workpiece at particular parameter values can be discerned through scanning electron microscope (SEM) analysis, yielding significant insights. parameters that have been identified provide practical recommendations improving method utilised. Understanding entirety facilitated SEM microstructures under conditions. morphology evaluated using profilometry, provides additional insight into integrity. discourse investigates potential applications implications results, as well suggests directions further study concerning enhancement processes similar alloys.
