Experimental investigation and modeling of drilling process parameters for surface roughness of Al6061/SiC/Gr hybrid composite using RSM

Surface quality and material removal rate (MRR) are two significant factors in the manufacturing which influence precision thus mirrors the productivity of the industry. Objective of this work is motivated to determine the optimum operating parameters for the drilling Aluminum hybrid composite. The metal hybrid composite of Aluminum was fabricated by stir casting process. Silicon carbide and graphite particles were added to improve material properties. The main cutting parameters, namely, spindle swiftness, feed amount and type of coolant are considered in this study. In this work, the experimentations were planned by a Box-Behnken design (BBD) method. The impact of procedure parameters on the reactions are assessed and ideal cutting conditions for limiting surface roughness and boost the MRR were resolved utilizing reaction tables, reaction charts, association tables, 3-D surface plots and attractive quality investigation. To approve, affirmation tests have been completed and anticipated outcomes have been seen as in great concurrence with experimental discoveries.
