    This study evaluated the operating point and the suction performance of the suction module for carbon fiber reinforced plastics (CFRP) dust removal under different drilling rotational speeds. A three-dimensional steady-state Reynolds-averaged Navier–Stokes (RANS) calculation with a shear stress transport (SST) turbulence model was conducted to investigate the internal flow characteristics and system resistance of the base model. Parts of the suction module exhibiting an unstable flow behavior were determined and their shape was modified for increased aerodynamic and suction performance. Prototypes of the base and the modified models were fabricated for measurement of the operating point and efficiency of the CFRP dust removal. Results confirmed the selection of appropriate blower specifications for the drilling system design of the modified suction module to achieve high efficiency and high suction.
