Reasons for Errors in Laser Cutting Machine Processing

There are many problems in the use of metal fiber laser cutting machines, including errors in the laser cutting process, poor laser cutting results, and so on.

What are the causes of errors in metal fiber laser cutting machine processing:

1.Geometric error of workpiece

Due to various reasons, the surface of the processed object is undulating and heat is generated during the cutting process. In this way, the surface of the thin plate part is easily deformed, and due to the uneven surface, the position of the laser focus and the surface of the processed object will also be different. The ideal position changes randomly.

2.The cutting thickness of the material exceeds the standard

The cutting material thickness exceeds the standard.
Take 3000W as an example: the thickness of the plate that the laser cutting machine can cut is less than 20 thicknesses. The thinner the plate, the easier it is to cut and the better the quality. If the sheet is too thick, the laser cutting machine will be more difficult to cut. Under the condition of ensuring the cutting, there will be errors in the processing accuracy, so the thickness of the sheet must be determined.

3.Errors caused by programming

In the processing of fiber laser cutting machine, the processing trajectory on the complex curved surface is fitted by straight lines, arcs, etc. There are errors between these fitting curves and the actual curves. These errors make the relative position of the actual focus and the surface of the processed object and An error occurs in the ideal programming position. And some teaching programming systems will also introduce some deviations.

4.The occurrence of focus position error during laser cutting

In the cutting process of the fiber laser cutting machine, there are many factors that cause the relative position between the focus and the surface of the processed object to change, which are also related to the surface smoothness of the processed product, the clamping method of the workpiece, the geometric error of the machine tool, and the long time of the machine tool. Deformation of the load, thermal deformation of the workpiece during processing, etc. will cause the laser focus position to deviate from the ideal given position (programmed position).
