The first part of the theoretical section of the paper discusses plasma cutting technology. It mentions the history of plasma cutting, the working principle, plasma gases, applications in industrial sectors, advantages and disadvantages of the processes, plasma cutting procedures, and types of industrial plasma cutting automation. The process of plasma cutting is described from the activation of the current to the emergence of the plasma jet towards the workpiece. The plasma cutting procedures are described along with their modes of operation, advantages and disadvantages, types of cutting materials, cutting speeds, and material thicknesses. The characteristics of using specific gases are defined to improve the selection process. Plasma cutters are described, and safety measures to be followed during usage are outlined. In the experimental part of the study, copper was cut using a plasma cutter operating with compressed air. The selection of the plasma cutter, compressor choice, and the pros and cons of plasma cutting with compressed air are described. Towards the end of the theoretical section, copper is described as a material. In the experimental section, cutting was performed, and roughness was measured while tensile strength was tested. The equipment used for cutting 3mm copper sheet is described. Different parameters of speed and current intensity for cutting copper yield variations in the obtained samples. After plasma cutting, the samples were subjected to milling machining to achieve desired shapes and dimensions. The roughness of each cut sample was measured, and the samples were later tested on a tensile testing machine, where the tensile strength of the material adjacent to the cutting area was measured. A conclusion was drawn based on the obtained results.
