Why errors occur during the use of fibre laser cutting machines

When it comes to fiber laser cutting machine, many people’s first impression is that it is accurate, fast and efficient. Then in the process of using fiber laser cutting machine often appear many problems, such as errors in the process of laser cutting, laser cutting out of the finished product effect is not good, etc.. Many people do not particularly understand this, these errors are how to produce it? The following will follow GOLD MARK together with a look at it.

1.the geometric error of the workpiece

Due to various reasons, the processing object surface undulation, and in the cutting process, will produce heat, so the surface of the thin plate parts are easy to deformation, and due to the surface is not flat, will also produce the laser focus and the surface of the object being processed and the ideal position of the position of random change.

2.the cutting thickness of the material exceeds the standard

Cutting material thickness exceeds the standard. To 3000W for example: the laser cutting machine can cut the thickness of the plate below 20 thickness, the thinner the plate, the easier it is to cut, the better the quality. If the plate is too thick, the laser cutting machine cutting up more effort to ensure that the cut off, processing accuracy There will be errors, so to determine the thickness of the plate factor.

3.the error generated by programming

In the processing of fiber laser cutting machine, complex surfaces on the processing trajectory is fitted by straight lines, arcs, etc., these fitted curves and the actual curve there are errors, these errors make the actual focus and processing object surface relative position and the ideal programming position error. Some of the programming systems can also introduce some deviations.

4. Focal point position errors in the laser cutting process

In the cutting process of fibre laser cutting machines, the relative position between the focal point and the surface of the object to be processed changes due to many factors, and the smoothness of the surface of the processed product is also related to the way the workpiece is clamped, the geometric error of the machine tool and the long time load of the machine will be deformed, the thermal deformation of the workpiece in the process will cause the laser focal point position and the ideal given position (programmed position) deviation.

These random errors cannot be avoided and can only be reduced by online inspection and control, thus improving the accuracy of the fibre laser cutting machine.
