Application of Taguchi and Anova Methods in Selection of Process Parameters for Surface Roughness in Precision Turning of Titanium

Summary The objective of this study is the selection of cutting data (such as nc, f, ap) and tool materials (PCD, ceramic, CBN and carbide cutting tools) in order to improve the surface roughness in precision turning operation of parts made of pure titanium (GRADE 2). Machining parameters and tool materials are considered as input parameters. The surface roughness is selected as the process output measure of performance. A Taguchi approach is employed to gather experimental data. Then, based on signal-to-noise (S/N) ratio, the best sets of cutting parameters and tool materials specifications have been determined.
