Study On The Turning Process Of High Temperature Nickel‐based Superalloy Inconel 718

Abstract: In this work the research is conducted cutting force and surface roughness on the high speed turning process for Nickel‐based superalloy Inconel 718. The experimental investigations and statistical analysis have been carried out to study the effect of cutting parameters (speed, feed and depth of cut) on cutting force. Also has been carried out the effect of cutting speed and depth of cut to surface roughness. The orthogonal experiment is applied to coated carbide tools turning high‐temperature alloy Inconel 718 and factorial design of experiments compliance to 9 run (3k) was following for the experimental design. Analysis of variance (ANOVA) is used to study the effect of process parameters and establish correlation among the cutting speed, feed rate and depth of cut with respect to surface roughness and statistical analysis was perform on MINITAB 17.
