EXPERIMENTAL INVESTIGATE EFFECTS OF CUTTING TOOLS ON SURFACE ROUGHNESS AND MRR OF EN31 (ALLOY STEEL) TURNING OPERATION ON CNC MACHINE

Abstract

This paper introduces an experimental work of material removal rate and roughness characteristics of surface roughness create CNC turning on EN-31 composite steel (alloy steel). In this test essential three machining parameters is developed based on experiment the experiment carries out consider machining parameters cutting speed, feed rate, depth of cut. Three types of cutting tool turning inserts are use for turning on EN-31 material. Insert material is carbide at relative other coating material it is physical vapor deposition, chemical vapor deposition. Analysis of experiment adequacy of the models of material removal rate & surface roughness has been established with the analysis of variance (ANOVA) throw present.
