What is the reason for the wrong cutting error of sheet metal fiber laser cutting machine?
There are many reasons for the error of the sheet metal fiber laser cutting machine:
- Geometric error of the workpiece.
Due to various reasons, the surface of the processed object of the fiber metal sheet fiber laser cutting machine is undulating, and heat is generated during the cutting process. In this way, the surface of the thin plate part is easily deformed, and due to the uneven surface, laser focusing and processed objects will also be generated. The position of the surface changes randomly from the ideal position. The roughness of the cut paper. Generally, the smoother the surface of the cut material, the better the cutting quality.
The thickness of the cutting material exceeds the standard. Generally, the thickness of the sheet that can be cut by a sheet metal fiber laser cutting machine is less than 12 thicknesses. The thinner the sheet, the easier it is to cut and the better the quality. If the plate is too thick, the sheet metal fiber laser cutting machine will be more difficult to cut. Under the condition of ensuring the cutting, there will be errors in the machining accuracy, so the thickness of the board must be determined.
- The error caused by the workpiece clamping device.
The workpiece to be processed is placed on the worktable. Due to machining errors and long-term wear between the workpieces, the cutting bed will appear uneven, and this unevenness will also produce random errors in the position between the thin steel plate and the laser focus.
- Programming error.
In the processing of fiber metal sheet fiber laser cutting machine, the processing trajectory on the complex curved surface is fitted by straight lines, arcs, etc. There are errors between these fitted curves and the actual curves, which makes the relative position and ideal position of the actual focus possible. And the surface of the processed object. An error occurred in the programming position. Some teaching programming systems also introduce some deviations.
- The laser output power does not meet the standard.
When the sheet metal fiber laser cutting machine is running and debugging, it is necessary to ensure that the laser output power reaches the standard. Generally, the higher the laser output power, the better the cutting quality on the same thickness of the board.
- The focus position is incorrect.
If the focus of the sheet metal fiber laser cutting machine is not aligned, it will directly affect the cutting accuracy, so it must be calibrated and checked before running. You can also purchase Primapress auto-focus laser head when you buy the machine to auto-focus to ensure cutting accuracy.
- Processing speed. The cutting speed of the sheet metal fiber laser cutting machine directly affects the processing accuracy. Therefore, it is necessary to achieve the best match between cutting speed and material before operation.
When working on a sheet metal fiber laser cutting machine, we must take it seriously. Under normal circumstances, due to these random errors, it is difficult to avoid geometric errors of the workpiece, errors caused by the workpiece clamping device, and errors caused by programming.
