In the process of using the fiber laser cutting machine, errors sometimes occur, which has a certain impact on our cutting accuracy. What are the reasons for this error? Next, let the staff of Xinquanli Laser introduce the reason.

1. Geometric error of workpiece

Due to 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 parts is easy to deform, and because of the uneven surface, the laser focus and the position and ideal position of the surface of the processed object will also change randomly.

2. Error caused by workpiece clamping device

The processed workpiece is placed on the needle-shaped worktable. Due to the processing error and the wear between the workpiece and the workpiece for a long time, the needle-bed will be uneven, which will also produce the random error of the position between the thin steel plate and the laser focus.

3. Error due to programming

In the process of laser cutting, the machining path on the complex surface is fitted by lines, arcs, etc. These fitting curves and actual curves have errors. These errors cause errors in the relative position and ideal programming position of the actual focus and the surface of the machining object. Some teaching programming systems also introduce some deviations.

We cannot avoid these random errors. We can only reduce the errors through online detection and control to improve the accuracy of the fiber laser cutting machine.
