SiCp/A383アルミニウム合金複合材料の旋削被削性 Turning machinability of SiCp/A383 aluminum alloy composite
Turning machinability test were performed on the SiCp/A383 aluminum alloy composite by measuring tool wear, cutting resistance and surface roughness. Shapes of flank wear were changed from band type to triangle type with increase of flank wear. The flank wear were increased with increasing of both cutting speed and cutting distance. The flank wear of the first stage of cutting was very large regardless cutting conditions. It was more than 0.2 mm on cutting distance of 50 mm. Regardless side rake angle, cutting resistance were increased with increasing of both cutting speed and cutting distance. In case of cutting speed on 1.67 m/s, finished surface roughness in the first stage of cutting was large, but finished surface roughness was changed for better with increasing of cutting distance. In case of start of cutting on cutting speed of more than 3.33 m/s, the finished surface roughness become better increased with increase of cutting distance. However finished surface roughness suddenly increased with increase of tool wear.
