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.

硬质合金刀具表面织构与分形分析

这项工作突出了多尺度分形和表面纹理分析在通过电解磨料珩磨 (EAH) 工艺加工硬质合金切削刃时的有用性。为了实现这一目标，我们研究了新鲜（未处理）切削刃样品和通过电解磨料珩磨（处理）加工后的相同样品的表面纹理和材料特性，为制造商提供可持续的优势来强化他们的工具。通过评估每个样品区域中的四个相似位置，分析了未处理和珩磨样品的表面特征。扫描电子显微镜 (SEM) 已用于表征材料表面。发现未准备好的切削刃和样品的电解磨料锋利表面区域可以通过区域尺度分析和表面纹理特征来区分。本研究将有助于改进工具的寿命估计，并强调对工具和工件之间的润滑机制进行统计建模的机会。
