Tool wear is a very unavoidable phenomenon that affects the overall performance of cutting tool during machining. Improvement in tool wear leads to deformation in surface finish and an increase in cutting force. Poor surface finishes influence the product quality and raise the product cost as well as machining cost. In this study, the copper oxide (CuO) nanoparticles have mixed with vegetable oil (coconut oil) to enhance the machining property of tungsten carbide (WC) cutting tool. The performance of WC cutting tool inserts have been investigated in, wet, vegetable oil and CuO nanoparticles based vegetable oil cutting environment. Turning of EN 8 steel has been done by kepeing constant cutting parameters viz. speed, feed, and depth of cut. The tool wear has measured in terms of flank wear, and nose wear. Results reveal that the addition of CuO nanoparticles into the vegetable oil reduces the tool wear and surface roughness significantly.
