Since the widespread application of fiber laser cutting machines, the production efficiency in the field of metal processing has significantly improved. Due to the high cutting accuracy, small cutting seams, fast speed, and small cutting deformation of the fiber laser cutting machine, the quality of the processed products is far superior to traditional cutting processes. Nowadays, laser cutting equipment holds a significant proportion in the metal processing industry.
Any machine will encounter some problems during use, and the same applies to laser cutting machines. For example, in the process of laser cutting metal, although the parameter settings are clear, cutting errors may still occur. In this situation, we need to find the cause of the error in order to adjust and solve the problem, ensuring the accuracy of the fiber laser cutting machine.

Reasons for cutting errors in fiber laser cutting machines:
Uneven surface of metal materials
When the surface of the processed metal material is uneven or contains small particle residues, due to the default setting of the cutting process for flat sheet cutting data, the uneven surface of the metal may cause uneven heating during cutting in different areas, causing the thin plate to overheat and melt, while the thick plate area may not be able to melt through.
Programming error
In the processing of fiber laser cutting machines, the machining trajectory on complex surfaces is fitted using straight lines, arcs, etc., but there is an error between the fitted curve and the actual curve. These errors result in errors between the actual focus and the relative position of the material surface and the ideal programming position.
The actual thickness of the metal material exceeds the cutting range
For example, a 1000W fiber laser cutting machine can cut up to 12mm carbon steel plates. If a 14mm carbon steel plate is forcibly cut, even if it can be cut through, there will definitely be errors or slag hanging at the bottom. So before cutting metal, it is necessary to determine the thickness of the plate and the actual thickness that the laser equipment can cut. Plates that exceed the cutting thickness range cannot guarantee their quality accuracy.
Focus position error
During the processing of fiber laser cutting machines, errors in the focus position can also lead to errors during cutting. Many factors can change the relative position of the focus and the surface of the product, which can also affect the accuracy of the metal workpiece. For example, the level of placement of the machine tool itself, the degree of wear of the bed rack, etc. Before working on the fiber laser cutting machine, check to reduce cutting errors.
The above are the reasons for the errors in the fiber laser cutting machine. You can investigate them according to the specific situation. The correct use of laser metal cutting equipment can effectively avoid cutting errors and obtain high-precision metal workpieces.
