Metal laser cutting machine in the application of the whole process will produce a lot of problems, involving in the whole process of laser cutting error, laser cutting effect is poor and so on, so how to cause such error?Then small make up for you to answer.

1. Geometric error of parts

Based on the direct impact on a variety of reasons, processing object surface uneven, and in the whole process of laser cutting, can lead to temperature, so very easy to deformation on the surface of the sheet metal parts, and based on the rough on the surface, can cause the laser focus and be processed objects on the surface of the parts and ideal type parts generate random variation.

2. The thickness of laser-cut plates is beyond the standard

The thickness of laser cut material sheet is above standard.Take 3000W as an example: the thickness of the board with laser cutting function is below 20 board thickness. The thinner the board, the easier the laser cutting is and the better the quality.If the plate is too thick, laser cutting machine laser cutting up very difficult, in the guarantee of the case of cutting off, processing accuracy will produce error, so to clear the plate thickness of the plate element.

3. Errors caused by programming

In the production steps of fiber optic laser cutting machine, the processing trajectories on complex surfaces are fitted by straight lines, arcs, etc. There are errors between such fitting curves and actual curves, which cause errors between the relative parts on the surface of the actual focusing and processing objects and the ideal programming parts.Some gait analysis programming systems also introduce some biases.

4. Error of focusing position in the whole process of laser cutting

In the whole process of fiber laser cutting machine laser cutting, focus and be processed objects on the surface, many changes occurred in the relative positions of elements, related to processing products surface smoothness is the same way, parts clamping, machine tools and machine tool geometric error, load for a long time will produce deformation and thermal deformation of parts in the production step leads to the laser focus parts and parts of the ideal type of a given (programming) skewed.

There is no way to avoid such random errors, so the error can only be reduced by online detection and control, so as to improve the task accuracy of the optical fiber laser cutting machine.
