본 연구에서는 자동차 및 기계부품의 제조공정에서 핵심부품인 밸브바디의 주물공정 후 생성된 버(burr)를 제거하기위한 초음파 디버링 장치를 개발하고자하였다. 초음파 디버링장치는 진동부와 제어부로 구성되고 디버링효과의 극대화를 위해 디버링 수에 포함된 용존가스의 제거가 매우 중요함에 따라 용존가스 제어기법을 적용한 초음파 디버링 장치를 개발하고 평가실험을 수행하였다. 본 연구에서는 초음파 디버링에서의 용존가스에 따른 디버링 성능을 평가하고 실제 시스템에 적용하기위한 산업적용 가능성 평가를 수행하였다.

본 논문에서는 유연 공구 홀더를 가진 다관절 매니퓰레이터 로봇을 이용한 디버링 시스템에 대한 연구를 수행하였다. 로봇을 이용한 디버링 작업에서 버 공구(Rotary file)의 강성과 로봇의 강성으로 인해 작업 시 발생할 수 있는 각종 오류를 방지할 수 있는 소형의 3자유도 유연 공구 홀더(Flexible Tool Holder)를 개발하여 이에 대한 분석을 하였다. 개발한 유연 홀더를 새로운 구조의 다관절 로봇 매니퓰레이터를 이용하여 디버링 시험을 수행하였다.(중략)

The modern aircraft consists of tens/hundreds of thousands of components. A large proportion of these components are manufactured using a machining process. A deburring process must be performed after to machining. This study investigates the effect of changes in the deburring wheel rpm on the deburring force and radius. The deburring wheel is used to trim sharp edges off machined parts of the aircraft. The deburring wheel used consists of a core and a nylon hair(this new concept is protected under patent). We find that higher deburring wheel rpm results in increased deburring force and radius. For deburring wheel rotation rates of 500~750rpm, deburring force of 3.4~6.5kgf and deburring radius of 0.4~0.5mm were observed.

A new design for deburring tools for intersecting holes is introduced. The tool tip is mounted on a slender cantilever assembled into a circular shank. The tool tip has been design to cover ranges of exit angle and diameter ratio between intersecting holes. The design is an improvement over the previous ones by the authors. Experiments have been performed on AL6061. With the new design, mild exit burrs with exit angles greater than 45$^{\circ}$ are successfully removed. For large burrs with smaller exit angles, however, the deburring could be incomplete.

Deburring is conducted using MAF(magnetic abrasive finishing) method. Magnetic inductor is designed and manufactured to generate proper magnetic induction far deburring the burr formed in drilling SM45C. Rotational speed, table feed rate, grain size of powder and working gap are changed to investigate the effect on deburring.
