Optimization of Process Parameters on CNC milling machine for Mild steel IS 2062:2011 E250 Gr. A with AlTiN coated tool insert in wet condition

Abstract

Now a days manufacturing industries wants to increase the quality of product and reduce manufacturing cost. The aim of this project work is to reduction of energy consumption during the machining phase, reduce surface roughness and increase material removal rate by optimization of face milling process parameters of mild steed IS 2062:2011 E250 Gr A with Taguchi orthogonal array. 27 experimental runs based on L27 orthogonal array of Taguchi method were performed. Spindle speed, feed rate and depth of cut this process parameters are optimized with multiple performance characteristics such as surface roughness (Ra), Material removal rate (MRR) and power consumption. The machining operation performed on VMC by using coolant with 63 mm cutter diameter. The analysis of variance (ANOVA) is also applied to identify the most significant factor using Minitab software. The analysis can be done on AlTiN insert coating. At the last conformation test were performed.
