“…However, the radius of the cutting edge is the most commonly used parameter for symmetrically honed edges, and optimizing this radius has been the most common approach to bring about improvements through micro-geometry variation. 4,10,11,[24][25][26] In this study, the cutting micro-geometry is characterized by cutting edge radius measurement. Cutting edge radius on the edge profile were measured using Zeiss Surfcom 1500 surface texture cum form measuring equipment.…”

Cutting-edge micro-geometry is a crucial factor influencing chip formation and tool performance. This paper investigates the effects of varying cutting edge radius (36–70 µm) on machinability and chip morphology during finish turning Ti6Al4V. An increase in edge radius decreases the cutting to thrust force ratio and produces lower chip thickness due to the increase in plowing zone depth. The machining temperature for the 48 and 52 µm edge radius tools is lower compared to all other tools. At the initial stage, the edge prepared tools exhibit larger flank wear, whereas subsequent flank wears progression is slower for the prepared tools as compared to the sharp tool. BUE and premature chipping is reduced for larger edge radius tool due to better edge stability provided by cutting edge preparation. Beyond the 59 µm edge radius, the process force, machining temperature, tool wear, and surface roughness increased steeply due to the increase in the size of the plowing zone. In addition to cutting force and machining temperature data, surface roughness, tool wear measurements and XRD analysis show that a radius range of 50–55 µm results in optimum performance for finish turning Ti6Al4V.

“…Additionally, the resulting surface topographies made by modern multi-process manufacturing technologies are very complicated. They may contain patterned structures with sharp edges or randomly distributed grains [4,5]. Therefore they cannot be directly assessed based on statistical parameters.…”

“…But the variability of the edge radius can be as high as 38% and mostly along the same edge. Yussefian and Koshy (2013b) suggested an innovative edgehoning process using electrical-discharge-machining (EDM) to reduce the variability of the edge generated. In addition, a foil electrode was used as the counter face to hone the carbide inserts with the complex geometric features (Masuzawa & Kimura, 1991;Yussefian, Koshy, Buchholz, & Klocke, 2010).…”

This work highlights the usefulness of multi-scale-fractal and surface-texture analysis in the machining of cemented carbide cutting edge by electrolytic-abrasive honing (EAH) process. In order to achieve this, a fresh (untreated) cutting edge sample and the same sample after machining by electrolytic-abrasive honing (treated) were studied upon their characteristics of surface texture and material properties to provide manufacturers a sustainable advantage in strengthening their tools. The surface characteristics of untreated and honed samples have been analyzed by evaluating four similar locations in the regions of each sample. Scanning electron microscopy (SEM) has been used for the characterization of materials surface. It was found that the unprepared cutting edge and the electrolytic-abrasive sharp surface regions of the samples could be distinguished by area scale analysis and surface texture characteristics. The present study will help in improving the life span estimation of the tools and highlight the opportunities for the statistical modeling of lubrication mechanisms between the tool and the workpiece.
