Analytical determination of wear resistance criteria of a stamping tool for various loading conditions

Introduction. The paper is devoted to the analytical determination of general criteria for predicting the wear resistance of heavily loaded friction couples, in particular, stamping tools, operating under various loading conditions. The proposed system of criteria is based on physical dependencies that link the basic wear index, i.e. the number of loading cycles NF with crack resistance parameters n and C. The work objectives were the development and analytical foundation of the calculation technique that provides for predicting the wear resistance of the stamping tool for various loading conditions, as well as the predetermination of experimental verification of the efficiency of the developed methodology.Materials and Methods. Mathematical models that link the key criterion of wear-resistance, the number of loading cycles NF with crack resistance parameters nand C, are proposed. An analytical verification of the proposed models is carried out.Results. Mathematical models are developed for predicting the wear resistance of a stamping tool operating under various loading conditions...
