A Study on the Machining Characteristics for Micro Barrier Ribs by using Micro Endmilling

마이크로 엔드밀에 의한 미세격벽가공의 가공특성에 관한 연구

Recently, miniaturization and mass production are the main trends in manufacturing fields. Therefore, ultraprecision machining and MEMS technology have been taken more and more important position in machining of microparts. Micro endmilling is one of the prominent technology that has wide spectrum of application field ranging from macro parts to micro products, such as PDP and IT components, in precision products manufacturing. However, the deburring is significant problem in making smooth and precise parts in micro endmilling. This paper shows removal characteristics of burr generated by micro endmilling process. Additionally, it is necessary to understand the formation mechanism of burr of micro barrier ribs to find proper deburring method.
