The processing method for the shaking of the cutting head of the fiber laser controller at any time

During the processing of fiber laser cutting equipment(RDC6563FG, RDV6563FG-NET), if there is significant shaking of the cutting head when it follows the height, it will not only affect the cutting stability, but may also cause a decrease in the quality of the cut or even collision with the plate. To address this issue, the following methods can be used for troubleshooting:

1. Poor contact between the amplifier housing (or metal plate) and the machine tool:
   If the amplifier housing or metal plate has poor contact with the machine tool, it may lead to electrical noise or unstable grounding, which can cause the cutting head to jitter. To ensure equipment stability, check whether the amplifier housing is securely connected to the machine tool. If poor contact is found, readjust the position or replace the connection method to ensure reliable electrical grounding and mechanical connection.

2. Capacitor calibration is inaccurate or not performed:
   The movement of the cutting head is controlled by the servo system, and capacitor calibration directly affects the system's ability to precisely control the cutting head position. If the capacitor calibration is inaccurate or has not been performed, it may result in position deviations and irregular jitter. The solution is to recalibrate the capacitor to ensure that the calibration results meet the standard, thereby improving control precision and reducing jitter.

3. Sheet metal jitter caused by blowing air:
   During the cutting process, air is often blown to maintain cleanliness and cooling in the cutting area. However, if the airflow is uneven or the air pressure is too high, it may cause the sheet metal to jitter, which affects cutting stability. In this case, appropriately increasing the jitter filtering time can effectively smooth the impact of airflow on the cutting process, reducing the jitter of the cutting head.

4. Excessive rigidity setting of the servo driver:
   If the rigidity setting of the servo driver is too high, the cutting head may respond too sensitively to input signals, causing large oscillations or resonance, which leads to jitter. To resolve this, the rigidity setting of the servo driver should be appropriately reduced to balance response speed and stability, avoiding the negative effects of excessive rigidity.

5. Significant machine interference and poor grounding:
   If there is significant electromagnetic interference around the machine or the grounding system is unstable, it may cause noise and electrical interference, resulting in cutting head jitter. In this case, strengthen the grounding measures by connecting the high-level PGND of the controller to the machine's housing and ensuring the housing is properly grounded. Additionally, in environments with high interference, consider using filters or shielding technologies to further reduce external interference's impact on the system.
