Optimization of Cutting Force and Surface Roughness Based on Taguchi Technique for AA6061

Abstract-Optimization of machining parameters has great concerned in manufacturing environments, there for in this study cutting force and surface roughness are optimized based on machining parameters. Many researchers have established the relationship between the surface roughness and machining parameters, but less attention has been paid to tool shape and geometry, in this study tool flute is first time used as machining factor beside cutting speed, depth of cut and feed rate. Response Surface Method and analysis of variance are adopted to establish the relationship of machining parameters to the surface roughness and cutting force using Taguchi technique. Optimization of cutting force and surface roughness are simultaneously adopted, either by optimized cutting force or surface roughness. The minimum surface roughness obtained is 0.2398 µm with corresponding cutting parameter is 12.01 N.
