The structures of airplane consist of sheet metal part, heavy machined part, and so on, which generate enormous amounts of cutting chip when these parts are machined. The cutting chip detoriorates the part quality and production efficiency. Therefore, cutting chip collecting apparatus is necessary for better quality and efficiency. In this study, blowing type cutting chip collecting apparatus was newly proposed and the concept design of the apparatus was examined through numerical analysis. Computations using the mass-averaged implicit 2D Navier-Stokes equations are applied to predict the nozzle flow field. The standard k-e turbulent model are employed to close the governing equations. Consequently, this study shows that the suggested blowing type cutting chip collecting apparatus can be alternative to existing expensive chip collecting apparatus.

A single-piece-machined-part has superior characteristics to an assembly of several pieces of part especially for aircraft components. It is neccesary to develop high efficient 'multi-head router machine' for machining a large size single-piece-part on a large scale. In this type machine, many cutting chips are generated. These chips should be removed automatically for productivity and part precision. In this research, cutting chip collecting apparatus for 'multi-head router machine' was designed. A suction-type-blower (20 HP, Δp3,000㎜Ag), which was attached to the machine tool directly, was very effective.
