PARAMETRIC ANALYSIS OF SURFACE ROUGHNESS (SR) AND MATERIAL REMOVAL RATE (MRR) OF HARDEN STEEL ON CNC TURNING USING ANOVA ANALYSIS: A REVIEW

摘要

Surface roughness is a major consideration in modern Computer Numerical Control (CNC) turning industry. Most existing optimization researches for CNC finish turning were either accomplished within certain manufacturing circumstances, or achieved through numerous equipment operations. Therefore, a general deduction optimization scheme is deemed to be necessary for the industry. In this study, an attempt has been made to investigate the effect of cutting parameter (cutting speed, feed, depth of cut) on surface roughness (S.R) and material removal rate (MRR) during machining of Harden Steel. The experiment were conduct on a CNC turning center using cubic boron nitride (CBN) insert. The results are analyzed using analysis of variance (ANOVA) method.
