Investigation and Optimization Key Parameters Effect on Cutting Feasibility of Electroless Ni-CBN on Carbide End Mill Cutting Tools by Taguchi Method

Abstract Nowadays, coated cutting tools are extensively used in the cutting manufacturing industry, which gets to the important developments in cutting tool performance and economy thru reducing tool wear of cutting tools, low cutting forces, and better-quality surface roughness of the workpiece. From this research, the effects of feed rate, spindle speed and depth of cut on the surface roughness using electroless Nickel-CBN coated cutting tools (carbide) were measured experimentally. The parameters of machining’s setting were determined by using Taguchi’s L9 (33) was used in this study. The S/N ratio with analysis of response in optimization and ANOVA results were used to recognize the best significant parameters affecting the surface finish. From this experiment, the outcome shows that the feed rate parameter most affected to the surface roughness. The optimum setting parameter’s levels are spindle speed 3, feed rate 3, and depth of cut 2. So, the optimum machining settings are spindle speed of 3450 rpm, a feed rate of 334 mm/min, and depth of cut 2 mm.
