An analysis of end milling performance on B4C particle reinforced aluminum composite

The present work investigates the influence of cutting parameters on the output responses such as temperature rise, chip formation, delamination, tool wear, and surface roughness during end milling of stir cast AA6351-B 4 C composite. The titanium nitride (TiN)-coated solid carbide tool with four flute end mill is used for the experiments. The thermography and scanning electron microscopy (SEM) images are used to analyze the effect of temperature rise on the chip formation and chip behavior. The increase in feed considerably increased the chip thickness from 0.7 to 1.2 mm at 2000 rpm. In addition to that, the formation of abrasive tool wear at minimum cutting speed has resulted with an increase in surface roughness. Further, the delamination of the slot entry surface is also assessed and achieved a lower delamination factor (
