Optimization and Process Parameters of CNC End Milling For Aluminum Alloy 6082

The study aims at optimization of cutting parameters in CNC End milling of Aluminum Alloy 6082. CNC milling is a versatile and most widely used operation in present industry. Sur face quality affects fatigue life of components and influences various mechanical properties and has receive d serious attention for many years. In this work,experiments are conducted to analyze the surface roughnes s using various machining parameters such as Spindle speed,feed rate and depth of cut . The data was used to devel op surface roughness prediction models as a function of the machining parameters. In the present study,CNC machining centre with Cemented carbide end mill of 25mm diameter and 30� helix angle was used. A multiple regression analysis is used to correlate the relationship between the machining parameters and surface roughnes s. RS methodology was selected to optimize the surface roughness resulting minimum values of surface roughness and their r espective optimal conditions. Key words:CNC end milling,Aluminum alloy 6082,Taguchi,ANOVA
