A Study on the Characteristics of Cutting for A16061-T6

A16061-T6재의 절삭가공 특성에 관한 연구

This study carried out a cutting experiment on Duralumin A16061-76, which is light but strong and highly anticorrosive, so recently popular as a lightweight material, by changing cutting conditions and alternating 4 insert tips, and examined the effect of each insert tip on cutting force at certain cutting conditions, the measurements of the coarseness of processed surfaces roughness, and the chip workability. The 1311owing conclusions were drawn from the results. Cutting force for cutting tool is when insert tips were alternated at each cutting condition, the cutting force of cutting tools was highest then CBN tools were use(1 next by Ceramic tools, Cermet tools, and WC tools. Therefore, WC tools are considered most suitable for cutting Duralumin A16061-T6. Surface roughness as for the coarseness of surfaces according to insert tips applied to Duralumin A16061-T6 under the cutting condition of depth of cut below 1mm, feed rate below 0.24mm/rev and cutting speed over 100m/min the coarseness of material surface roghness appeared to be finest when WC tools were used, next by Ceramic tools, Cermet tools, and CBN tools.
