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.

Abstract: A measuring system for measuring the accuracy of the position and track of a machine element moved along a predetermined track. The system includes a predetermined track along which a machine element moves relative thereto and a measuring device for measuring the position of the machine element along the track. The track has a guide of the measuring device, on which a carriage is guided along the track, wherein the machine element can be fastened to the carriage. A component of the measuring device is fastened on the carriage and a drive integrated with the measuring device moves the carriage in a controlled manner along the guide into predetermined positions and at predetermined speeds.

Abstract: A measuring arrangement suitable for checking the geometric and dynamic accuracy of two numerically controlled machine elements which are displaceable with respect to each other. A base body is fastened on a carriage of a machine tool to be tested, on which a linear guide with a linear measuring device is rotatably seated. A measuring element is fastened in a spindle of the machine tool and is connected via a guide with the carriage. The measuring element has three pivot bearings and a further linear guide, as well as further measuring devices for measuring the rotating movements around the pivot bearings and along the further linear guide. Thus the measuring arrangement has six degrees of freedom, wherein four rotary and two translatory joints make possible the registration of individual deviations.
