Magnetic Thin Film Coating on TNMG Tool insert by Physical Vapour Deposition and its Analysis

Abstract

The purpose is to study the effect of various cutting parameters Spindle speed, feed rate and depth of cut by turning process on SGI 600/3 with uncoated, coated, and coated and magnetized tool insert of tungsten Carbide tool insert. Coating on tool insert is by Physical Vapour Deposition method. Experiments were conducted on VTL and the influence of cutting parameters on Tool Insert was studied using Design of experiments. Optimize cutting parameters to increase Tool life. Development of a fully automated machine tool has been the goal of modern manufacturing industries research for decades. This can be accomplished until the fool proof and practical methods to sense the amount of tool wear and the development of wear resistant cutting tools are developed. The purpose of these coatings is to increase the tool life. TNMG tools are used for turning purpose; its tool life is very less as compared to other types of tools. Coating of nickel chromium is essential and promising for TNMG type of inserts. Increase in tool life will increase the batch production.
