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.

Recently, the deburring process which is last process of manufacture is one of the important process for complete product. The development of shape guided automatic deburring machine is essential because manual deburring process has very irregular quality and higher error rate as well as consider irregular shape radius. In order to develop of shape guided automatic deburring machine, in this study, we conducted 3D design, assembly, machine simulation and structural analysis using CATIA. Also, we conducted to make automatic deburring machine and conducted a performance test.

A high speed deburring machine was developed based on the analysis of magnetic contact force, forced vibration, stiffness and deformation of the structure. After 3 dimensional CATIA modelling, the stiffness and the deformation properties of the deburring machine in static and dynamic condition using finite element method were analyzed. Both static and dynamic simulation results showed that designed high speed deburring machine was well satisfied the stability properties at the operating condition. we have performance test program for the real system to evaluate the simulation results.

The machining technology for the removal of micro-burr has been demanded because electrode parts of electron gun have minute holes. In this study, Magnetic Assisted Polishing(MAP) is applied to remove the micro-burr instead of the contentional polishing process such as the etching and barrel. Optimal polishing conditions are selected from many experiments using the tool of the flat end slit type. On the basis of experimental results, the deburring machine for the Magnetic Assisted Polishing of electrode part is developed and its performance is evaluated.
