| Abstract | This study aimed to study the biogas simulation with mixed gas free on metal cutting by using oxy-fuel to cut AISI 1045 metal size 50 mm. X 50 mm. X 6 mm. with automatic cutter model KT 5 NX. In general biogas was composed of methane, carbon dioxide, hydrogen sulfide and oxygen. However, this study employed only 67% methane and 26.3% carbon dioxide using Biogas 5000 as a measuring instrument. The results showed that the average surface roughness was 4.94 micrometer measured by Mitutoyo SURFTEST SJ-301 with the heat measured by SEM JS-5410 LV at 1000 magnification. The cut was divided into 4 sections i.e. the highest flame-cutting part, unequal heat radiation parts and less heat part. Heat was analyzed qualitatively by EDS Link ISIS300 to find changed elements. From 4 areas there were 9 elements, among these iron, carbon and manganese were necessary elements. After cutting, average carbon was higher at 0:42-00:50 while normal was 0.73%. Iron was below average at 76.35% from 98.51-98.98 whereas manganese was 0.58% which was similar to normal at 0.60-0.90%. |
