Abstract

— Coatings are well known to improve the performance of cutting tools in machining application, such as
high-speed machining. Unfortunately, the development of cutting tool for high-speed machining of hard and difficult-tocut material has remain a problem for quality and economy of production. The present work studies the performance of
mono and dual material PVD coated tool in machining of austenitic stainless steel (AISI 304 steel) under high speed
turning. The coating material was used AlCrN, TiAlN and TiAlN/AlCrN. The influence of cutting parameter (cutting
speed, feed rate) on work piece surface finish and tool life has been analyzed. The coating thickness was measured using
SEM analysis and coating material test was done using EDS analysis. The surface roughness of the work piece was
measure using Surface Roughness Tester. Tool flank wear of the tool was measured using Tool maker microscope. The
wear mechanism at the end of tool life was investigated in detail using scanning electron mi croscope (SEM). An attempt
has been made to analyze the effects of process parameters on Machinability aspects using Taguchi technique. The
statistical analysis of variance (ANOVA) is applied to investigate effects of cutting speed and feed rate on tool li fe and
work piece surface roughness. The main aim of thesis work is to study effect of mono and dual materials coating on
tungsten carbide tool.
