OPTIMIZATION OF CNC PROCESS PARAMETERS ON INCONEL 625 USING RESPONSE SURFACE METHODOLOGY

This paper examines the effect of cutting parameters and machining conditions on workpiece surface when turning Inconel 625 solid round bar by using PVD coated (TiAlN/TiN) carbide tool. CNC Turning was conducted under two cutting conditions, namely Dry and Wet. CNC turning process parameters determined by using Taguchi L9 orthogonal arrays and effect of turning process parameters, i.e. Cutting speed (m/min), feed rate (mm/min) and depth of cut (mm) are examined for two output aims, i.e. Surface Roughness and MRR. In this study, it is originated that the cutting condition, feed followed by the depth of cut, and cutting speed plays more significant task on the selected response parameters.
