Performance of PVD Coated on High Speed Steel Cutting Tool in Industrial Applications

Abstract

An experimental investigation of mechanical properties of TiN and AlCrN Coated cutting tools have been performed at room Temperature. HSS single point cutting tool is taken as substrate material. Aluminium chromium nitride (AlCrN) and Titanium Nitride (TiN) is applied by physical vapour deposition method. Vaporized and condensed form of the desired film material on to various work piece surface is generally known as Physical Vapor Deposition (PVD). The finished product’s surface finish is increased by the coated tool and hence it reduces the cost of quality control process in industry. In uncoated HSS tool, the tool frequently requires replacement or reconditioning, which is not required for TiN and AlCrN Coated cutting tool and hence it reduces the cost for replacements .In PVD coating, the tool life is increased about 7.5 times compared to the uncoated cutting tool. For the factor of cost analysis, the cost required for making an AlCrN coated cutting tool is drastically reduced and increased life of tool also reduces the cost to procure a new tool or replacing an old one.
