Beschreibung

Cemented carbide tools are widely used in machining. New shank tools made of cemented carbide are usually produced by grinding cylindrical blanks. In consideration of global shortages of raw materials and increasing material costs, the use of worn tools as blanks for the production of new carbide tools represents a promising alternative. This article presents a novel process chain for recycling of cemented carbide milling tools. However, the geometry of the worn tool results in complex engagement conditions as well as varying loads on the grinding wheel in the re-shaping process. Thus, process strategies aiming to control the varying loads on the grinding wheel and to ensure a stable grinding process are analyzed. Based on the results a suitable grinding strategy is selected.
