Abstract

The purpose of this research is to determine the effects of current variation to the cutting kerf and hardness in medium carbon steel cutting process using CNC Plasma Arc Cutting. This research uses experiment methods to study the effect of a given treatment. The electric current were varied for 20, 25, 30, 35, and 40 amps. The test parameters were cutting kerf and hardness. The data were analyzed using descriptive statistics. The test result shows that there are differences in cutting kerf and hardness. The lowest kerf and hardness value was obtained from the 20 amps current, with a kerf of 1.64 mm and a hardness of 707.4 HV. The highest kerf and hardness value was obtained from the 40 amps current test, with a kerf of 2.58 mm and a hardness of 857.7 HV. This research concludes that the variation of electric current in CNC Plasma Arc Cutting process of medium carbon steel affects the kerf (99.59%) and hardness (94.17%).
