Abstract

Abstract: Ultra-precision cutting (UPC) is an advanced machining process capable of fabricating components with a surface finish and dimensional accuracy in the nanometer range. The cutting tool edge should possess ultra-sharpness and controlled waviness to bring off a higher degree of finish and accuracy. It also should have high hardness, toughness, thermal resistance and chemical inertness. As the cutting-edge radius is in order of nm, the edge characterization is always arduous. Profound knowledge regarding the wear patterns of the UPC tools is indispensable as it will affect the machining quality to a great extent. Hence, to employ a cutting tool for UPC operations, one should know the different variants of UPC and their characteristics, different tool materials and their properties, geometries and how it affects machining accuracy, various edge preparation method and characterization techniques and their limitations, associated measurement errors, tool wear patterns and processes to control the wear. These diverse areas have to be brought under a single roof to systematically choose the material, geometry, and fabrication method for UPC tools. This article provides a comprehensive review of the research related to cutting tools of UPC to understand and evaluate the current trends in the development of UPC tools. Graphical abstract: UF0001
