What causes the error of metal laser cutting machine?

1. Geometrical error of workpiece

Due to the influence of various reasons, the surface of the processed object is uneven, and in the cutting process, heat will be generated, so that 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 processed object surface will change randomly.

2. The cutting thickness of the material exceeds the standard

The thickness of cutting material exceeds the standard. Take 3000W as an example: the thickness of the plate cut by the laser cutting machine is less than 20. The thinner the plate, the easier it is to cut,

The better the quality. If the plate is too thick, the laser cutting machine is hard to cut. In the case of cutting, the processing accuracy will be error, so the thickness factor of the plate should be determined.

3. Programming errors

In the process of optical fiber laser cutting machine, the machining path on the complex curved surface is fitted by lines, arcs and so on. There are errors between these fitted curves and the actual curves. These errors cause errors between the actual focus and the relative position of the machined object surface and the ideal programming position. And some teaching programming system will introduce some deviation.
