State of the art of tool texturing in machining

Abstract

In most of the machining processes, the application of surface texturing is one of the most remarkable and promising research fronts in relation to the use of tribological concepts for improving machinability. This paper aims to review the most recent articles on this theme (from 2016 to date) to assist the researchers in the state of the art of this technology, guide the forthcoming related investigations, and thus, fill the identified research gaps. The texture effect in machining was comprehensively reviewed considering chip formation, cutting forces, cutting temperature, lubrication, surface integrity, and tool life. The present review highlights and summarizes the major findings with emphasis on the influencing parameters, such as workpiece and tool material, cutting process, lubri-cooling condition, texture geometry, and texture manufacturing technique. The overwhelming majority of the studies presented tool surface textures manufactured by laser ablation on the rake face of uncoated WC-Co tools. In this relation, turning was identified as mostly used machining process and dry condition as the chiefly implemented lubri-cooling environment. Moreover, most of the textures were noticed with linear grooves and dimple geometries, whereas the work materials mostly investigated were the hardened/high alloy steels and titanium alloys.
