Therefore, it is nowadays not only used in the processing of<br />natural stone, but also increasingly deployed on dismantling of nuclear or industrial plants. In this<br />field of application, concrete, reinforced concrete and steel have to be cut. In particular, the<br />processing of reinforcements and steel structures results in higher process forces compared to the<br />machining of natural stone or concrete. Consequently, the diamond wire is deflected leading to<br />decreased cutting performance in terms of the material removal rate. To overcome these challenges,<br />the diamond wire can be pretensioned which directly affects the stiffness of the tool. Thereby, the<br />deflection of the diamond wire can be reduced and the material removal rate can be increased.<br />This paper presents initial results concerning the influence of the wire pretension on the process<br />behaviour of a diamond wire when cutting steel S355JR. For these investigations, the wire<br />pretension was varied in a range of 300 N up to 2000 N. For the evaluation of the process behaviour,<br />resulting process forces, cutting power, wire deflection and surface removal rate were analysed. ER -
