Experimental-Numerical Analysis of Hot Forging Process with Monitoring of Heat Effects

Abstract

The paper deals with the experimental-numerical analysis of the hot forging process on a hammer, where the main focus is on monitoring the thermal effects that occur in this metal forming technology. This includes measuring and numerically estimating the temperature fields in the workpiece and forging tools in multi-stage forging process. For this purpose, a thermal imaging camera for measuring the temperature in the industrial process and Simufact.forming software for numerical modelling of the process using the finite volume method were used. The results presented in the paper show that the complementary application of numerical simulations and industrial measurements enables the identification of thermal effects on both, workpiece and tools, in the entire technological process of multi-stage forging, through precise determination of input parameters for numerical simulations by infrared thermography.
