PT Journal AU Handrik, M Saga, M Pechac, P Kopas, P TI Analysis of Force Conditions of the Hot Forming Machine in Rolling-Out of Bearing Rings SO Manufacturing Technology Journal PY 2015 BP 821 EP 825 VL 15 IS 5 DI 10.21062/ujep/x.2015/a/1213-2489/MT/15/5/821 DE Design; Optimizing Process; Hot Forming; Tool Life AB The main parameters of the hot forming machines are production capacity and the fatigue life of the used tools. The life of a tool depends on its shape and load. The load depends on the structural design and speed of forming. The goal of our paper is to present the structural optimization and technological parameters design with respect to tool life. This process is applied in the case of the hot forming machine analysis.
