Abstract

Ceramic reinforced aluminum matrix composites are increasingly gaining importance because of their specific, particulate reinforced physical features. Machining such materials is a time-consuming process due to their superior physical properties. Moreover, only a few recorded research documents discuss the optimization of machining parameters in the milling of aluminum-titanium diboride (Al/TiB2) composites. Thus, the current study sought to evaluate the effect of process parameters on the face milling machining process while machining Al/TiB2 metal matrix composite. Reinforcement weight percentage, cutting speed, feed rate, and depth of cut used in milling were used as input parameters in the Taguchi-DEA ranking methodology to evaluate performance metrics, including material removal rate and material's arithmetic average roughness. According to the results of the experimental investigation, cutting speed and reinforcement weight percentage have a greater influence on determining performance metrics in the milling process due to their role in determining impact strength. Among the selected process factors, the ideal combination of reinforcing weight percent (9%), cutting speed (1500 rpm), feed rate (300 mm/min), and depth of cut (0.15) were discovered and evaluated using a confirmation test with 3.14 and 2.34 percent variation in material removal rate (MRR) and surface roughness (Ra) values, respectively
