| Abstract | ||||
| Plasma Arc Cutting (PAC) is one of the most promising manufacturing technologies. In metalwork industry, it is a primary operation to prepare sheets and strips for later welding and/or machining operations. The cutting accuracy and surface quality have great effects on the time and cost of the preceding operations. Although PAC has many advantages for cutting different metals, it is used a little bit in cutting pure copper sheets. However, it has been observed that some factories are utilizing this operation in daily production without a sound scientific base. This is because the research in this area is rarely considered and consequently the effects of the operation variables on its parameters are not deeply investigated. In this research, the use of PAC for cutting pure copper is investigated experimentally. The aim of this investigation is to study the effect of the cutting variables on the cutting parameters. The studied cutting variables are current intensity, cutting linear speed, torch height, and plasma gas pressure. The interested cutting parameters are material removal rate (MRR), surface roughness (Ra), geometric error (Conicity) and the length of the heat affected zone (HAZ). The results are plotted and some explanations are given based on the previous work survey in this field. The results give guidelines to industry for better practice in the field of cutting pure copper using PAC. | ||||
