AlTiN코팅 층수에 따른 플라스틱금형강의 절삭특성에 관한 연구 = A Study on the Cutting Characteristics of Plastic Mould Steel According to AlTiN coated Layers

다국어 초록 (Multilingual Abstract)

This parer investigated into process characteristics of AlTiN coated layers for machining to the direction of upper and lower in plastic mold material (KP-4) with the cemented carbide ball endmill with the diameter of 8㎜ coated AlTiN layers (1~4) step by step using machining center. The material used in experiments was KP-4 that was machined by three types of inclined angles; 15°, 30° and 45° As estimated mechanical properties of AlTiN coated layers, it was shown the most result in the condition of three layered coating that the coating that the coating depth, the hardness of the coated layer and the surface roughness of the coated layer were 13㎛, Hv 3027.3 and 0.042㎛ , respectively. The cutting component was better at the condition of upper direction than that of lower direction in all experimental conditions and indicated to be less which the bigger angle of the material was increased the effective diameter of the tool.
