Abstract
The paper presents the results of experimental measurements and numerical calculations of temperature fields in the “die-moving wire” geometry configuration. Experimental measurements were applied for modelling boundary conditions for numerical models and their verification. Boundary element method (BEM) was used in mathematical modelling of basic differential equations and the technique of subdomains was used to combine different temperature fields in the tool and workpiece into a common problem. This statement defines in short the nature of the new approach to numerical modelling of temperature fields in the technological process of metal forming.
