A SIMPLE METHOD OF SYNTESIS OF CARBON NANO TUBES (CNT) ON HIGH SPEED STEEL DRILLING TOOL AND EVALUATION OF PERFORMANCE WHILE MACHINING

Abstract

Crbon Nano Tube(CNT) based drilling HSS(18 4 1 ) tool is a coated tool with more hardness when used with drilling process it can work for longer periods of time without less tool wear and capable of machining different work materials. During machining Carbon Nano Tube(CNT) plays an important role with high hardness which act as a protecting shield on HSS drill tool surface against wear. Chemical vapor deposition method is used for synthesis of CNT on this tool. The gases used for this method is acetylene and argon which is very has less cost also this coating have less cost due to this advantage this can be commercially used for drilling. Three parameter Force, Torque and tool wear is analyze with different depth of cut on radial drilling machine while machining with ductile material. Experiment shows that force and torque produced while drilling is very less results less power consumption and heat generated while drilling on radial drilling machine.
