Cutting accuracy is an important part of measuring the quality of laser cutting machines, but the accuracy of laser cutting is not completely dependent on the equipment itself, but is composed of many factors, mainly due to the following factors:
1. The size of the spot after the laser beam passes through the focus.
The smaller the spot after the laser beam is collected, the higher the cutting precision, especially the smaller the slit, and the smallest spot can reach 0.01 mm.
2. The positioning accuracy of the workbench determines the repeatability of the cutting.
The higher the precision of the table, the higher the precision of the cutting.
3. The greater the thickness of the workpiece, the lower the accuracy and the larger the slit.
Since the laser beam is tapered, the slit is also tapered, and the stainless steel having a thickness of 0.3 mm is much smaller than the slit of 2 mm.
4. The workpiece material has a certain influence on the laser cutting precision.
In the same case, stainless steel has higher cutting precision than aluminum and has a smoother cut surface.
Errors in the machining dimensions are common faults encountered when machining with a laser cutter, which affects both production efficiency and production costs. The main reasons for the processing size error are as follows:
1. The signal line is not normal. The signal line needs to be replaced at this time.
2. The equipment and computer are poorly grounded. At this point, the device and the computer need to be well grounded.
3. The computer is not working properly. You need to repair your computer or replace it at this time.
4. The computer operating system is faulty or infected with a virus. Need to reinstall the operating system or perform virus killing.
5. The application software is not working properly. At this time, you need to reinstall the driver software for the software and motion control card.
6. The power supply is unstable or interferes with the signal. At this point, you need to install a voltage regulator or eliminate interference signals.
7. The machining program is not written correctly. At this point you need to check and repair the machining program.
8. The processing parameters are not set correctly. To reset the correct processing parameters.
