ABS engineering plastic materials have excellent corrosion resistance and chemical resistance and are widely used as key materials for improving lightweight and structural performance in automobile interior and exterior materials, aerospace, electronics, and precision machinery industries. Due to these characteristics, as demand also increases, efficient processing methods and attempts to lower processing costs are needed. However, there are many opinions that downward cutting is more advantageous than upward cutting in end mill processing, and research on surface roughness cutting conditions for upward cutting in engineering plastics is insufficient. In this paper, we analyze the effect of upward cutting on surface roughness and present it as basic data for cutting conditions in upward cutting required for industrial sites by providing optimal data for cutting conditions
