Description
Advanced Control Function:
1. Sheet material surface height tracking control (follow-up function)
The Z axle allows sheet material surface height tracking control to adapt to different evenness of sheet materials.
The function is integrated in the CNC system, and provides quicker response, better sensitivity and higher
servo precision compared to conventional CNC system.
2. Laser power ramp control:
During acceleration and deceleration of the CNC laser cutter, PA8000 CNC system can adjust the laser power
ramp according to the real time speed of the CNC laser cutter to ensure consistent quality of processing section.
The function is also integrated in the CNC system, and provides quicker response and better instantaneity
compared to conventional CNC system.
3. Self-adaptive feed forward “ART” regulation technology:
The self adaptive feed forward “ART” regulation technology allows the PA8000 CNC system to make self
adaptive regulation during motion control on real time basis. The CNC laser cutter position control closed loop
can reach the optimal gain and the best rigidity. The “zerolag” feature of “ART” regulation technology makes
the CNC laser cutter has the minimum servo lag error and the highest position servo accuracy.
4. Rollback function:
If the laser cutting stops due to failure, the machine can cut the work piece previously being cut again after
returning along the outline path of the work piece to prevent scraping the work piece.
5. Breakpoint return function:
If the laser cutting stops due to failure, the X, Y and Z motion axles can be moved; the cutting nozzle is repaired
or replaced; the machine is returned to the breakpoint and restarted to begin cutting to prevent scraping the
work piece.
6. Automatic frame-finding function:
After loading material, the operator needs not to accurately position the sheet material. Through automatic
frame finding, the CNC laser cutter can automatically confirm the position where the sheet material is placed
and automatically adjust the programmed angle of the coordinate system to adapt to the position where the
sheet material is placed.
No human accurate positioning of the sheet material is needed any longer, thus significantly reduces labor
intensity, makes the operator load material more easily, and improves the efficiency.
