Micro Structural Analysis of Coated Carbide Tools on Tool Wear and Surface Quality during Dry Machining of Stainless Steel 304

Abstract

Machining of difficult-to-machine materials has always been a prime area of investigation for researchers. With regard to that tool wear and surface roughness are some of the most important machinability indicators to evaluate the performance of machining processes. This study on micro machining of SS 304 using coated and multilayer carbide tools. In this work, the influence of machining parameters on tool wear and surface roughness is studied. Furthermore, the tool life has been improved by coated tools. Comparatively less irregular surface while machining with coated tools tools. The research is also complemented with a short chip morphology study. The present work recommends the use of multilayer coating on carbide tools for machining of SS 304 under dry conditions using different parameters with optimized Taguchi methods
