Abstract
The use of aluminum with a reinforced coefficient to increase this material compared to aluminum is used in automotive, aircraft and locomotive industries, in this article, while examining the cutting force and erosion of tools on the machining process of composite aluminum in different percentages of SIC, the machining characteristics are investigated. The end milling operation is performed to obtain the minimum cutting force, tool wear with the maximum removal rate using gray relational analysis based on response surface design method (RSM). Twenty-seven experimental runs were carried out based on the response surface design method (RSM) by changing the parameters of spindle speed, feed and depth of cut in different weight percentages of reinforcements such as silicon carbide (SiC-5%, 10%, 15%). and alumina (5-5% Al2O3) in the aluminum metal base 7075. Gray relation analysis was used to solve the multi-response optimization problem by changing the weights for different responses based on quality or productivity process requirements. Proper selection of input parameters (spindle speed 1000 rpm, feed 0.03 mm/rev, depth of cut 1 mm and 5% SiC) produces high material removal rate with fine surface, less tool wear and low cutting force.
