Original Abstract

A turning knife enters a work piece during turning. Due to friction, heat is produced proportionate to the turning speed. The resulting temperature influences the quality of the machined surface and wear of the knife. Thus, new machine tools must be developed which minimize the production of unwanted heat. To accomplish this task, a new experimental device has been prepared, where thermocouples were built into the knife and surface thermocouples were welded onto its surface. The measurement process was supplemented by thermovision. Heat flux and surface temperatures were computed from the subsurface data using a one-dimensional inverse task. A detailed temperature distribution on the surface of the turning knife was determined using a combination of these methods.
