Abstract
The thermographic examination of functional surfaces of forming tools in the forming process is important for the selection of an optimal tool material or an optimal coating material for a particular forming process and for a particular workpiece composition, and also for the optimization of process parameters of the forming process. The task of the present invention is comprised therein, to develop a device and a process, which enables the rapid and simple thermographic examination of functional surfaces of forming tools during the forming process. This task is solved by a process and a device, in which the sought after temperature distribution of the functional surfaces during the forming process are conducted, from point of origin, through a channel, in the direction of a temperature measuring device, via thermal radiation or, in certain cases, thermal conductivity.
