THE TECHNOLOGY OF THE OXY-FUEL CUTTING ON A CNC MACHINE

Popis výsledku v původním jazyce

The technology of oxy-cutting is a widespread solution for thermally cuttable materials nowadays. This article discusses the use of oxy-cutting technology on CNC machines. This technology is particularly suitable for unalloyed and low-alloy steels and cast steels. With the help of this technology, it is possible to cut sheets ranging from 3 to 1000 mm. For sheets with a thickness of 20 mm it is preferable to use a laser or plasma technology. When cutting with an oxy-fuel the workpiece it is initially heated on the surface up to the ignition point and then the oxygen intake is opened. Its purity must be at least 99.5%. The workpiece is thus melted and oxygen blows out the liquid metal of the kerfs with a combustion heat formation. The combustion heat heats up the layer below again reaching the ignition point. Thus this process continues endogenously until the whole sheet is burnt through the whole thickness of the part. The resulting quality of the oxy-fuel cutting is determined by many factors, some of which can be affected by the proper selection of a CNC machine, and others during machine operation, and by the proper parameter settings of the oxy-fuel cutting itself. The article also describes the main parameters of the oxy-fuel cutting to achieve the desired parameters of the cut and of the product. The adjustable settings of the cutting compensations in the program have a significant impact on the cuttings. By setting the compensation or technological allowance of the cut, the torch is moving at a certain distance from the component, in order to maintain the desired dimension of the component/cut. For cutting the external contours this compensation is positive, and for cutting the internal contours the compensation is negative.
