Abstract

It has been well established that advanced surface coatings on cutting tools improve wear resistance by modifying the contact conditions between the chip and tool interface. As a result of the recent developments in cutting tool industry, coated tools have made a significant contribution to the metal cutting operations in terms of tool life, cutting time and machining quality. The challenge of modern machining industries is focused mainly on the achievement of high quality, in terms of work piece dimensional accuracy, surface finish, high production rate, less wear on the cutting tools, economy of machining in terms of cost saving and increase the performance of the product. In general, the most important point in machining processes is the productivity, achieved by cutting the highest amount of material in the shortest period of time using tools with the longest life time. The present research work describes the development, Mechanical, Tribological performance of Nano material coating of TiN,TIC, on Tungsten Carbide cutting tool. The Mechanical, Tribological properties of TiN,TIC, are to be compared with uncoated Tungsten carbide cutting tool. And also different coating methods like Chemical Vapour Deposition, Physical Vapour Deposition Method, can be used for comparision.The present work will help to find the tool life and wear behaviour of the each coated tool and it will help to find the best tool coating applicable for the cutting tool. The experiments of Mechanical, Tribological properties tests have to be conducted as per ASTM standards. SEM analysis has to be done for investigating the surface morphology of Tungsten Cutting tool. The coated cutting tool have to be modelled using suitable assumption and analyzed by means of finite element method using ANSYS software. Both results of Experimental and ANSYS software are to be compared.
