Optimisation of the machining parameters for a cylindrical grinding operation helps to save time, cost, and influence to get better surface characteristics and surface finish. The study deployed the Taguchi technique. The scrutinised factors included the feed rate, work speed and the depth of cut (DOC). Experimental set up involved the L9 orthogonal array. Minitab® and Microsoft® Excel 2016 generated results after applying the design of experiment. The Ra was tested by using a portable surface roughness tester. The silicon carbide wheel and a hydraulic cylindrical grinder machine were used. After analysing the generated results, DOC was found to be statistically significant. The influential parameter of Ra was found to be DOC as it contributed to 45.3% and 58.6% before and after heat treatment processes, respectively.ensurface roughnessoptimisationTaguchi methodsEN45 materialAISI 9260machining parametersheat treatmentaffinity diagramdesign of experimentorthogonal arrayanalysis of varianceANOVAgrinding processDeployment of the Taguchi technique for surface roughness optimisationJournal Articlehttps://doi.org/10.1504/ijise.2020.10028682
