알루미늄 합금의 미세조직 개선에 의한 절삭 가공 특성 향상

Machining Characteristics Elevation by Micro-structure Improvement of Aluminum Alloy

This research has been carried out to experiment machining characteristics by elements addition and subtraction of AC8B and sample that is used fur car piston materials. 1.Mechanical properties of development sample expressed unique mechanical properties than AC8B. 2. Cutting resistance of development sample decreased about 10% than AC8B according to increase of the cutting speed. 3. According to increase of the feedrate, all comparison workpiece found that specific cutting resistance decrease. 4. It was found that sample's machining characteristics that is developed by addition and subtraction of elements improves.
