The error causes of metal laser cutting machine in the use of metal laser cutting machine will appear many problems, including the laser cutting process of error, laser cutting effect is poor, so how these errors are generated?
The geometric error of the workpiece is affected by various reasons, the surface fluctuation and fluctuation of the processing object generates heat during the cutting process, which makes the surface of the thin plate parts easy to deform. Due to the uneven surface, the laser focus varies randomly with the position and ideal position of the surface of the processed object. 2. The cutting thickness of the material exceeds the standard of the cutting material. Take 3000 W as an example, the thickness of laser cutting plate is less than 20 W. The thinner the plate, the easier the cutting, the better the quality. If the plate is too thick, laser cutting machine is more difficult to cut, in the case of ensuring cutting, machining accuracy will have errors, so it is necessary to determine the thickness of the plate. 3. The programming error in the machining process of optical fiber laser cutting machine, complex curved surface machining path by a straight line, arc fitting, fitting curve and the actual curve is error, the error cause actual focus and process on the surface of the object relative position error between the ideal programming position and, some teaching programming system can also bring some deviation.
In the cutting process of optical fiber laser cutting machine, the focusing position error occurs in the laser cutting process of sample 02. Many factors change the relative position between the focus and the surface of the processed object, which is also related to the surface smoothness of the processed product. The clamping mode of the workpiece, the geometrical error of the machine tool and the long time load of the machine tool will deform. The thermal deformation of the workpiece during machining will result in the deviation between the laser focus position and the ideal given position (programming position). For these random errors, it is unavoidable. Only through on-line detection and control can the errors be reduced, so as to improve the working accuracy of optical fiber laser cutting machine.
