3D cutting of flat materials by combustion using fuel and oxygen. Beskrivning The process Process Combustion gas mixture [1] is burned at the cutting nozzle with the purpose of heating the material to the ignition temperature. Pure oxygen gas is supplied through the center of the die [2], which supplies the additional energy needed to carry out the actual cutting. This cutting beam [3] helps to melt and burn the material, and thus creates a cut in the workpiece [4]. Material residues is pushed away from the section of the oxygen gas in the form of a slag stream [5]. The oxygen purity and outflow rate, which is largely influenced by nozzle design, greatly affects gas cutting results. What fuel gas is chosen depends on several factors such as thickness of the workpiece and the time for heating. The cutting head is positioned usually by means of a portal system in combination with additional shafts to provide tilting and rotation. The systems are designed for angled cutting of flat plates and to some extent also for cutting curved surfaces but does not have the same slant opportunities and working range as full 3D cutting. Positioning can also be by means of industrial robots where the accuracy of position can be held within desired tolerances. By nesting details can be placed in a way that minimizes wastage of material.
