Performance of cutting tool in hard turning is significantly influenced by its microgeometry, such as edge radius. This study presents an experimental exploration to understand the effect of cutting edge radius on machining performance in terms of surface roughness and tool wear. The cutting tools (CBN) with three groups of nominal edge radius, 20, 30, and 40 μm, were used in the study. The cutting edge radii were characterized with an Alicona optical microscope, and variation of the edge radius was evaluated in this study. The machining tests were then conducted to experimentally assess the effect of cutting edge radius on surface quality and tool wear under different machining conditions. Three-level and two-factor experiments were designed in the test. The results in this study suggest that there is noticeable variation in the edge radius on a cutting tool with a certain nominal value of edge radius. The variations tend to be smaller with increase of the nominal value of edge radius. Besides, the results can be drawn that edge radii have a significant influence on surface roughness and tool wear. Considering all factors, the cutting tool with nominal edge radius of 30 μm demonstrate better machining performance among three groups of cutting tool in hard turning of AISI52100 steel.

“…Several researchers state [1][2][3][4][5][6][7][8][9][10][11][12][13] that the central goal of the cutting edge preparation process is to generate a specific geometry in the contour of the cutting edge (rounding or chamfer or combination of both), and to produce an improvement in the cutting edge micro topography (notchedness or chipping) and to adapt the surface of the cutting edge and cutting surfaces for the subsequent coating process of the cutting tool or for the improvement of the contact behavior for an specified machining application. The cutting edge micro geometry is often defined by the cutting edge radius r n .…”

In modern manufacturing industry it is essential to produce under low costs and high quality of products in a short time. This is possible by selecting the cutting parameters in order to achieve high accuracy and low processing time. Usually the desired cutting parameters are determined based on experience or by use of various handbooks but the cutting tool capability is not fully employed. The tool wear has detrimental effect on surface roughness and costs of production as well as on cutting tool performance and machining process reliability. The meso-and microgeometries of tool design have long been poorly considered by end users and by researchers, because of the lack of manufacturing procedure leading to accurate edge radius preparation. The problem of cutting edge preparation requires considering the appropriate integration of the following aspects: workpiece, machining process, machine tool, surroundings and cutting tool. The application of the edge preparation process seeks to solve this problem by means of the elimination of defects and irregularities and by the generation of defined edge geometry and by modifying the micro-topography of the edge and the micro-structuring of the face and flank of the tool. This article is an outline of literature knowledge concerning the cutting edge design and cutting edge preparation.

“…The geometry of the edge preparation influences the thermomechanic aspects of the cutting process. From which it is worth pointing out the format of the deformation zone, the temperature distribution in the cutting process, the machining forces, the chip formation and flow, the superficial integrity of the work piece and the tool's resistance to wear 2,[3][4][5][6] . Due to its importance in the machining field, cutting edge failures and some benefits related to the protection of the cutting edge achieved by different processes have been the subject of studies by several researchers [7][8][9][10][11][12] .…”
