The aim of this paper is to find out how the edge preparation of cutting tools affects cutting forces in milling. The theoretical analysis was focused on the cutting edge geometry, edge preparation and cutting forces. In the practical part of this paper is described the procedure of preparation and the process of the experiment in which was measured and watched the behavior of cutting forces on end mills with different cutting edge radius. Results from cutting force measurement are described and evaluated in the final part of this paper. These results were investigated in the process of machining of stainless austenitic steel (AISI 316L). The Kistler model 5070A dynamometer was used to measure the cutting forces. The results of the experiment showed that the cutting edge preparation has a significant influence on the cutting forces during milling.

“…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.

“…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] . This paper aims to understand the influence that cutting edge preparation has on the quality of the obtained hole and on the tool's wear resistance when compared to a simply sharpened tool.…”
