“…Experiment of Baksa showed that different quality of the cutting edge after grinding has a little effect on the cutting tool life [2]. The cutting edge geometry and the applied edge preparation methods affect the tool wear of cutting tools [10]. Cutting edge can be prepared with several methods of cutting edge preparation after grinding.…”

The paper deals with the comparison of milling tools geometry after drag finishing with various times. The aim was to determine the influence of drag finishing on macro geometry of the solid cemented carbide mills. The article describes tool geometry deviance after grinding process and the influence of drag finishing on rake angle, flank angle and diameter of the tools. The cemented carbide material with chemical composition WC + Co (10%) was used for this research. The tools were manufactured on the Reinecker WZS 60 grinding machine from cemented carbide rod. The tool geometry of cutting tools was measured on ZOLLER genius 3 optical measuring machine. The drag finishing process was carried out on OTEC DF-3 Tools drag finishing machine with OTEC SIX 70/16 grinding granulate. It was found the accuracy of cutting tools manufactured on grinding machine, and the deviation of rake and flank angles was 2° and tool diameter was 0.08 mm.

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.
