A scattering dust collector in automobile brake pads was investigated in this study. The dust scattering was measured by mounting a booth with a particle counter for both the vehicle-induced wind and brake caliper locations. In addition, the collection effect of the dust scattering was analyzed using the designed dust collector. The results of this study can be used to develop an advanced dust collector and the field test modes for dust scattering in an automotive brake system.

Accumulated dross adhered to the cutting support degrades the cutting accuracy and aggravates the working environment by reducing the efficiency of the dust collector. Furthermore, the cutting machine and product can be damaged by the scattering of molten metal. In this study, an attempt was made to increase the productivity of steel cutting process and improve the working environment by dross control. The dross adhesion characteristics were invested by a cutting experiment and the design concept for a dross removal machine was devised. Finally, a cutting support cleaning system and its operating algorithm were developed. The applicability of the developed system was examined and verified by a long-term field test after installation of the plasma arc cutting system of a shipyard.
