Abstract: — In today’s manufacturing industries there is an always demand and requirement of high rate of production, accurate dimensions, decrease in the cutting rate, increase in the quality of manufacturing machined part and machining of hard materials. In this experimentation work the machining and performance of uncoated carbide cutting tool and PVD Tin coated cutting carbide tool is experimented. The hard turning is done on hard material AISI 1045H and soft material pure aluminum under various parameters cutting speed, rate of feed and depth of cut. The machining is done under dry condition. The affect of various parameters of cutting tool and work material has been tested in experimentation work. The tool chatter vibration, surface roughness, tool wear is tested. The tool chatter vibration is measured by using Digital Vibration Meter (VM-8200) for both uncoated and PVD tin coated cutting tool in running conditions. The surface finish for tool material is measured by using Taylor Hobson roughness meter. In the last tool wear is measured by Scanning Electron Microscope (SEM) for both uncoated and PVD tin coated cutting tool. It has been found that hard turning on hard material at high speed, low rate of feed and high depth of cut is improved by using PVD Tin coated cutting tool and uncoated cutting too is good for soft material. The tool chatter vibration is very critical factor that’s affect on rate of production, dimensions, tool life, efficiency of machine, and etc. The high tool chatter vibration can break cutting tool that’s result on loss of material, decrease the rate of production, money loss, time loss. It is very essential to reduce tool chatter vibration, the various researches has been done on this factor but no researches exits that completely exit this factor. In this experimentation work the PVD TiN multilayer coating is used for minimization of tool chatter vibration that meets to the demands and requirements of today’s manufacturing world. The tool chatter vibration on uncoated cutting tool is high at high speed, low rate of feed and high depth of cut, whereas the tool chatter vibration on PVD Tin coated tool at same conditions is low. PVD Tin coated cutting tool give better performance as compared to uncoated tool. The surface roughness is also a very crucial factor that’s affect on the dimensions of the machined material and its quality. It is very necessary to achieve better surface finish. The PVD Tin coated cutting tool gives good surface finish as compared to uncoated tool. It also increases the life of tool that’s affect on performance and the demands and requirement of today’s manufacturing industries.
