본 연구에서는 마이크로 탄소 브러쉬 하전부와 평판형 금속 집진부로 구성된 저전력 소비형 2단형 전기집진기를 개발하였고, 특히 인체 위해성이 높은 $0.3{\mu}m$급의 미세한 오일 미스트에 대한 인가전압 및 소비전력별 집진효율 특성을 실험연구를 통해 고찰하였다. 하전부의 인가전압에 따른 단위 입자당 하전율과 입경별 집진효율을 측정함과 동시에 이론에 근거한 계산값과 비교해 보았으며, 9 주 동안의 장시간 운전을 통해 지속적으로 포집된 오일 미스트에 의한 전기집진기의 성능을 열유체역학적인 관점에서 변화를 조사하였다.

Dust collecting performance of cyclone collector for oil mist was alalyzed in the study. The purposes of using cutting fluid during cutting have been colling, lubricating, chip washing and anti-corroding. However, the present manufactaring industry restricts the use of cutting fluid because cutting fluid confains poisonous substances which are harmful to the human body. Also, the optimum design oil-mist collector. The new oil mist collector was designed. In the near future, this device must be tested in the real machining center and CNC machine. Cutting using oil-mist showed better cutting characteristics than dry, air and fluid cutting with respect to by cutting force, tool wear and surface roughness. The model(A, B Type cyclone) of the set of fixture and alveolus are made by using a CAE software. Finally, we have obtained a model A Type solution by using orthogonal array. Therefore, it could be confirmed that as the model-A was increased and model-B was decreased, cut diameter was decreased.
