Aspects Regarding Mechanized Thermal Plasma Cutting of Metallic Materials - Carbon Steel
Journal Title: RECENT - Year 2011, Vol 12, Issue 31
Abstract
The purpose of this paper is to present an up to date analysis concerning the status of mechanized thermal cutting procedures, which have to be taken into account when settling the manufacturing technology in industrial usage. In particular, this paper refers to the plasma thermal cutting procedures, which tend to be chosen by a large number of manufacturers that take into account very carefully the fragile balance between manufacturing costs and final product selling price. Thermal cutting definition refers to melting or burning cutting procedures applied on the base material by using the help of a thermal source. Among these classes of procedures, there are oxy-fuel cutting, electric arc, plasma and laser cutting. When classifying thermal cutting procedures, there were taken into account the achievements regarding quality levels specified inside SR EN ISO 9013:2003 Norm that refer to the mechanized cutting conditions. Prior to economical issues, quality conditions stipulated into standards or manufacturing norms have to be taken into consideration. Cutting accuracy, chamfer angle, surface roughness cutting width and thermally influenced area size are just some of the factors that determine the future working procedure. It is certain that the achievement of the quality. The mechanized cutting procedures are characterized by advantages and disadvantages that conditions stipulated into standards or manufacturing norms can be done only by using CNC automatic cutting machines have to be taken into consideration when settling the manufacturing technology.
