Effect of Cutting Variables of End Milling Process on Surface Roughness and Machining Vibrations
The end milling process is widely used in the manufacturing industries to produce numerous surface features. This research work aims to investigate the influence of spindle speed, feed and depth of cut on surface roughness and machining vibrations while carrying out end milling on AISI D2 die steel using uncoated, and Zirconium Nitride (ZrN) coated ball end mill cutters. Taguchi’s L9 orthogonal matrix is used to conduct the experiments. Analysis of variance (ANOVA) is used to find out significant factors affecting the cutting characteristics. Results of the ANOVA indicate that spindle speed is the most influencing factor concerning the performance outputs. It is observed that ZrN coated ball end mill results in better surface finish and lower machining vibrations.
