The paper deals with the issue of cutting edge preparation and tool treatment before the coating and their influence on the tool life of coated cutting tools. The aim was to examine the influence of cutting edge radius sizes on the tool life of cemented carbide turning inserts. Theoretical analysis was focussed on the issue of cutting edge microgeometry, discussing the classification and importance of cutting edge microgeometry. The most famous and used edge preparation methods are summarized in article along with the results of current research of famous tool companies and institutions. In this article, the tool lives of cemented carbide turning inserts which were prepared by several methods were compared. Cemented carbide turning inserts were deposited by AlCrSiN nanocomposite hard coating. Long-term tool live tests were carried out on DMG CTX alpha 500 turning centre. The tool wear of cemented carbide turning inserts was measured on Dino-Lite digital microscope during the turning. The tool lives of prepared cemented carbide turning inserts with required cutting edge radius and unprepared ones were compared. These results were investigated in the process of machining of austenitic stainless steel material X6CrNiTi18-10 by DIN EN (AISI 321), which shows higher strain hardening tendency.

Solid cutting tools are widely applied in the machining of shape parts and mainly fabricated using the grinding operations. Solid cutting tools are of specific geometry and shape. The tool geometry is created by mutual movement grinding wheels and stock. In the grinding of its manufacturing, grinding wheels are worn out gradually with the grinding number increasing. The wearing grinding wheel has a significant influence on the accuracy geometry of the tool produced. The paper focuses on the wear of the grinding wheels based on diamonds, and the grinding wheels based on cubic boron nitride. The wear rate of the grinding wheels is affected by the properties of a grinding wheel, grinding conditions, and type of cutting material. A measure of the ability of a grinding wheel to remove material is given by the Grinding ratio. The grinding ratio (G ratio) is defined as the volume of material removed (Vw) divided by the volume of wheel wear (Vs). Periphery grinding wheels were used in the experiments. Cylindrical face grinding was used for the machining of sintered carbide stock with a diameter of 20 mm. The results of the experiment show that the diamond-based grinding wheels are more suitable for grinding sintered carbide.
