N1 - Funding Information: The presented approaches for dust suction systems have all in common that the suction power is constant and not adjusted to the current dust concentration or machining conditions. Accordingly, most of the input power is not used efficiently. This thesis is supported by the research project NC Plus. Within the project, machine tools were examined with regard to their energy efficiency. It has been observed that the majority of the input power relates to the power demand of uncontrolled auxiliary units [8].

N2 - Fibre-reinforced plastic (FRP) are becoming increasingly important in aerospace and premium automotive applications. Usually, the manufacturing of FRP components requires dry machining which generates large quantities of dust. Because of their small size, the dust particles are extremely harmful to machine components and the operator’s physical health. To prevent long-term damage an effective suction system is required. Currently, extraction systems are subsequently integrated into conventional machine tools with no regard to energy efficiency. Hence, this paper introduces the development of an energy-efficient and intelligent dust suction concept for dry machining of FRP. Numerical flow simulations are used to investigate the effectiveness of a central suction as well as local suction at the cutting tool. In order to evaluate the newly developed concept, the amount of extracted particles along with the necessary volumetric flow rates are assessed. The simulation results demonstrate an improved dust particle extraction and an energy saving potential of up to 70%.
