고속 정면밀링 가공중 이송방향 진동에 관한 인자분석 = A Factor Analysis of Feed Direction Vibration during High Speed Face Milling Machining

다국어 초록 (Multilingual Abstract)

In modern manufacturing industries such as the airplane and automobile, material as aluminum alloy that is remarkable in respect of durability is effectively used. High speed machining technology for surface roughness quality of workpiece has been applied in these fields. Higher cutting speed and feedrates lead to a reduction of machining time and increase of surface quality. Furthermore, the reduction of time required for polishing or lapping of machined surfaces improves the production rate. Traditional milling process for high speed cutting can be performed with end mill tool. However, such processes are generally cost-expensive and have low material removal rate. Face milling cutter body has been developed using hyper duralumin to overcome disadvantage of traditional milling process. Cutting parameters, namely, feed rate, champer length, cutting speed and depth of cut are applied. In this work, design and analysis of experiments is conducted to study the effects of these parameters on the vibration by using the S/N ratio, analysis of ANOVA, and F-test.
