Information


Causes of error of metal laser cutting machine metal laser cutting machine in the use of many problems, including the error in the process of laser cutting, laser cutting effect poor, so how do these errors arise?

The following editor will give you an answer.

When cutting sample 011, the geometric error of the workpiece is affected by various reasons. The surface fluctuation and fluctuation of the processed object generate heat during the cutting process, which makes the surface of the thin plate easy to deform. Due to the uneven surface, the laser focus changes randomly with the position and ideal position of the processed object.2. The cutting thickness of the material exceeds the cutting material standard.Taking 3000 W as an example, the thickness of cutting plate of laser cutting machine is less than 20 W.The thinner the plate, the easier the cutting, the better the quality.If the plate is too thick, the laser cutting machine is more difficult to cut, in the case of ensuring cutting, machining accuracy will appear error, 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.

4. During the cutting process of fiber optic laser cutting machine, the focusing position error was generated during the laser cutting of sample 02, and many factors changed the relative position between the focus of the processed object and the surface, which was also related to the smoothness of the surface of the processed product.The clamping mode of the workpiece, the geometric error of the machine and the long time load of the machine will deform.The thermal deformation of the workpiece during machining will result in a deviation between the laser focus position and the desired given position (programmed position).For these random errors, it is inevitable, only through online detection and control can reduce the error, so as to improve the accuracy of optical fiber laser cutting machine.
