Seven processing methods (abrasive blasting, AFM, abrasive magnetic machining, drag, abrasive slurry (AS), B, and LM) were used by Bouzakis et al. [
43] for the edge preparation of cemented carbide-coated tools. Similar to drag finishing, abrasive slurry is a machining method that allows the tool to perform a two-stage planetary rotation movement in a liquid-abrasive mixed medium. Fig.51(a) compares the radius of the cutting edge after machining by these different methods; the findings showed that brushing can obtain a larger cutting edge radius under similar process conditions. The cutting experiments of four different metal materials (42CrMo4QT, AISI 304L, Inconel 718, and Ti‒6Al‒4V) were conducted using the prepared tools, and the effects of different cutting edges on the cutting performance of the tool were compared. Fig.51(b) summarizes the effect of different edge preparation methods on cutting tool performance during the cutting of different materials. The results indicate that the edge preparation of cutting tools is closely related to the cutting process. In particular, the inserts machined by DF have the longest life in cutting, whereas the tools machined by LM are the most fragile. Uhlmann et al. [
44] prepared microend-milling cutter edges by brush polishing, polish blasting, magnet finishing, and immersed tumbling. The morphology of the prepared edges is shown in Fig.52. The experimental results showed that the cutting tools prepared by immersed tumbling and magnet finishing have better cutting performance in milling. Wang et al. [
45] used brushing, drag finishing, and wet abrasive jet machining to prepare the cutting edge of K313 uncoated carbide inserts. The roughness
Ra of the edge surface increases only in wet abrasive jet machining. The cutting experiments were performed using unprepared and prepared tools. The tool prepared by drag finishing had the longest life under the same cutting conditions.
