Selection of cutting tool for desired surface finish in milling Machine using Taguchi optimization methodology

Abstract

In this paper, Taguchi's method for optimisation has been showcased to select a cutting tool on vertical milling machine when processing with (i) carbide insert tool and (ii) polycrystalline diamond tool, subjected to specify surface finish i.e., Ra 1.6 maximum. The milling machine parameters are validated for Depth of Cut (DOC), Feed Rate, and Cutting speed with tools configuration. The experiment results show that the different cutting tool with optimal milling parameter combinations provides variable surface finish values. After obtaining variable data, the analysis was conducted with the team's support and decided the best suitable tool for machining, providing a surface finish under a controlled limit. A comparative experiment has been shown to optimise the tool selection for procurement. A comparative study is being conducted between two tools one is of carbide and the second one is of polycrystalline diamond Analysis.of.Variance (ANOVA) is being applied to analyse the adverse effect of process parameters on the machining process. This work helps in the procurement during Design For Manufacturing (DFM) process. For this, the Taguchi methodology is being utilised to optimise tool selection. The research concludes that the Taguchi methodology is optimum for solving the nth issues with minimum trials and helps to select the tool.
