... with tungsten carbide by means of statistical reproduction of the delamination factor and machining force using Taguchi–Grey Relational Analysis. Design/methodology/approach The contemplated process parameters are Feed, Speed and Drill Diameter. The trials were carried out by taking advantage of the L-27...

... with the machining parameters, namely, helix angle of the end mill cutter, spindle speed, feed rate and depth of cut were optimized with considerations of multiple response characteristics, including machining force, surface roughness and delamination as the responses. PCA is adopted to find the weight factors...
