Computer Aided Manufacturing improves productivity in the modern manufacturing environment, however optimization of numerous factors involved in automated manufacturing or material removal environment is critical to produce high quality products. Recent advancements in manufacturing technology allow now a much wider selection of machining processes. In order to improve the accuracy, a long and expensive calibration process is usually performed on the CNC machine. In this thesis an attempt is made to investigate and evaluate the effect of different process parameters like cutting tool helix angle, speed, feed and depth of cut. 5083 aluminum alloy was selected as work material due to its wide range of applications in Automobile, locomotive and aerospace industries. The cutting speed in the range of 2000 rpm to 3500 rpm with a step of 500 rpm, feed of 800 mm/min to 1400 mm/min with a step of 200 mm/min, depth of cut of 0.25mm to 0.4 mm with a step of 0.05mm, Cutting tool helix angles of 25°, 45° Left hand helix and Right hand helix were chosen. The L16 design matrix was generated by using Minitab software. The machining is carried out as per the design matrix with HSS tool using SEMITOM AL 9002 oil as a cutting fluid. The process parameters were optimized using Single variable Optimization (Taguchi) and Multi Variable Optimization (Taguchi based Grey Relational Analysis) for better output response. The Analysis Of Variance (ANOVA) also carried out to know the percentage contribution of process parameters. From ANOVA it is found that Cutting speed and Feed are the most influential parameters for higher material removal rate. Feed and depth of cut are the most influential parameters for lower surface roughness.
