Mathematical model of cutting process of cutting tools with a side-mounted multifaceted, requiring no sharpening plates

Abstract

The article presents the results of experimental research of the cutting process with cutoff tools with laterally mounted multifaceted unresharpenable plates (MUP), which allowed to confirm their efficiency and progressiveness. As a result of research and experimental data processing, for the first time, the mathematical models were obtained that adequately describe force parameters (Pz and Py) of cutting process by the proposedcutoff tools. The rational values of rake and relief angles are determined.
