| Summary: | In recent years, remarkable developments have been made in die-sinking EDM, with its application broadening into new fields. It is necessary to considered surface finish and dimensional accuracy to accomplished high precision machining. The main objective of this project is to find the effect of surface roughness and dimensional accuracy on three different materials which are tool steel (AISI D2), aluminum alloy 6063 and carbon steel (AISI 1045). The variable parameter used is pulse on-time (5μs, 10μs, 15μs, 20μs, 25μs, 30μs, 35μs and 40μs). These three materials will be machined by using 4 pieces of copper electrode. As the result, surface roughness showed a proportion result against increasing pulse on-time. Dimensional accuracy showed inverse result as the pulse on-time increase. There are not much different found in the result. This might be the combination of pulse on-time used are too low to see the differentiation between the three parameters. |
