“…The test will be performed under the same conditions, blade sharpness, under the same unified perpendicular loading, and on the same bone sample. The saws will be tested following [14] with a cutting speed of 50 m/min and a feed rate f = 0.1 mm/rev. Further work will also involve the consideration of the result obtained in [17] stating that a spherical pit proves to be superior to a groove in meeting the various directions of chip flow and can provide a positive rake angle to the main part of the cutting edge, regardless of the chip flow direction.…”

“…It was also demonstrated that the tool coating is an important factor in the chip breaking problem. In the study [14], devoted to experimental work on cutting edges of different radii, 10, 50 and 60 µm, an advantage of the honing process in the form of having homogeneous and reliable cutting edges was demonstrated in contrast to ground inserts, the cutting edges of which failed rapidly. It was also emphasised that the lack of coating in the tool-chip contact area leads to a high wear rate.…”

Abstract. This work is devoted to the investigation of performance of surgical tools used in orthopaedics in terms of the occurrence of signs of necrosis, the accuracy of the cut and cutting tool design. For the comparison of the surgical tool performance different types of cutting devices were studied in a series of experiments. A Victorian surgical saw, its copy, a contemporary surgical saw, a surgical scalpel and an ultrasonic blade designed for a surgical application were chosen for the performance assessment. Such geometrical parameters as cutting edge shape, angle of teeth inclination, and sharpness of the cutting tools were analysed in terms of the quality of the cut and signs of necrosis. As a result of the analysis of experimental data obtained and theoretical insight the authors have come up with a creative solution for a novel design for a surgical ultrasonic blade which benefits from the design advantages of each of the analysed surgical tools and eliminates their drawbacks.

“…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 .…”

“…Table 2. Characterization of the insert micro geometry by "K" factor As mentioned [2] tool designers pay particular attention on the tool geometry at various scale: macro-geometry (cutting angles, chipbreaker etc. ), mesogeometry (cutting edge radius -order of magnitude: 1÷100 μm), and finally micro-geometry (surface texture -order of magnitude <1 μm).…”

Cutting edge preparation in machining processes

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.
