Evaluation Of Tool Wear & Surface Finish Of Aisi 316l Stainless Steel Using Nano Cutting Environment
Abstract- Demand for better surface finish and accuracy has been increased rapidly in recent years. A surface finish at macro
molecular level has become an important parameter for machining carbon nanotubes which have been of great interest both
from a fundamental point of view and for future applications. The most eye catching features of these structures are three
characteristics (mechanical, optical and chemical), which open a way to future applications. For commercial applications large
quantities of purified nanotubes are needed. Carbon nano tubes are to be mixed in a specific ratio (0.2%by wt.) with the
cutting fluid. The changes in certain properties are to be used to enhance the machinability during turning of AISI 316L
Stainless Steel. In the present work, cooling abilities of the fluid are assessed by carrying out machining tests using the fluids
with and without nanoparticles. Comparative study of tool wear, cutting force, workpiece surface roughness, and chip
thickness among dry machining, machining with conventional cutting ﬂuid as well as nano-cutting ﬂuid has been under taken.
This paper aims to optimize turning parameters of AISI 316L stainless steel. Experiments were carried out by plain turning of
48mm diameter and 600mm long rod of AISI 316L Stainless steel on all geared lathe at different cutting velocities and feeds
under wet machining with and without CNT inclusions. Machining tests were carried out using multi-layered TiN coated
ceramics inserts. The study reveals that the cutting force is reduced by using cutting fluids with CNT inclusion.
