“…A later figure of this paper will show that this time interval was sufficient to prevent the oxidation of the freshly generated surface. The tungsten carbide structure and the TiAlN+TiN coating of the pin are same as the cutting insert proposed in Wyen [17].…”

In order to represent actual cutting process conditions, an in-process tribometer is examined to measure friction during orthogonal turning process at cutting speeds up to 300m/min. The tribometer consists of a spring preloaded tungsten carbide pin with spherical tip mounted behind the cutting edge and rubbing on the freshly generated workpiece surface. The pin preload is set according to feed force. A 3D-force measuring device in the fixation of the pin allows evaluating friction coefficient from tangential and normal forces. Experiments show strongly different results when contacting fresh and oxidized surfaces and decreasing friction coefficient with increasing cutting speed.

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.
