Causes of errors in fiber laser cutting machine

When we use the fiber laser cutting machine, sometimes there will be errors, which has a certain impact on our cutting accuracy. What are the reasons for this error? Next, let our staff introduce the reasons for this.

1. Workpiece geometric error

Due to the influence of various reasons, the surface of the processed object is uneven, and heat will be generated during the cutting process. In this way, the surface of the thin plate part is easy to deform, and due to the uneven surface, the position and ideal position of the laser focus and the surface of the processed object will change randomly.

2. Error of workpiece clamping device

The processed workpiece is placed on the needle table. Due to the machining error and the wear between the workpiece and the workpiece for a long time, the needle bed will be uneven, which will also produce random errors in the position between the thin steel plate and the laser focus.

3. Programming errors

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

We can't avoid these random errors. We can only reduce the generation of errors through online detection and control, so as to improve the working accuracy of the fiber laser cutting machine
