Abstract

Over the last years, edge preparation techniques have become more common in tools industry. The shape, radius and surface finish of the tool edge play a significant role in the machining process. There are different edge preparation techniques, and each of them impacts differently on final microgeometry and, therefore, determinates its performance. In this work, two different edge conditions were applied on solid end mills. A detailed analysis of the preparation processes is presented, with the resulting form, radius and edge roughness of the tools. The materials, responsible for the edge preparation, are also presented. Finally, tool life tests and roughness analysis after dry and minimal quantity of lubricant (MQL) milling were carried out. From the presented results, it is possible to have more information on how the edge preparation processes can change the tool surface and the analysis makes also possible observing the interaction between the state of the edge and the application of MQL.
