The laser motion control system is located in the upstream group of the entire industry. It covers all aspects related to laser processing, such as typesetting, feeding, cutting and welding, by integrating key technologies such as computer-aided design, numerical control and computer manufacturing. It provides a complete system solution to ensure the good operation of all links, and is an indispensable component for the normal operation of laser equipment.
The main application scenarios of the laser motion control system are laser cutting, laser marking and laser welding, covering most metal and non-metallic materials, which can be said to be widely used. In daily processing and production, the precision, efficiency, stability and other indicators of laser depend on the real-time instructions of the motion control system. Therefore, it is critical to select a suitable control system.
Back to the laser motion control system, its core technologies mainly include the following five aspects:
1. Computer aided design technology: through computer modeling or reading the processing model from an external file, carry out graphic identification, editing and optimization, typesetting on the processing materials, and output the model to be processed.
2. Computer aided manufacturing technology: after the input of the processing model is completed, the laser processing instructions are output according to the relevant process requirements of materials, including laser power, pulse frequency, focus control, optical path trajectory, auxiliary gas, etc. With the help of the algorithm, the processing path is optimized, the drilling position is set, and the processing scheme of complex graphics is completed with the optimal solution.
3. Numerical control technology: output the operation instructions of external equipment such as motor, moving shaft and laser head, control the equipment to implement specific processing details, and cooperate with the laser output instructions to complete specific laser processing operations, which plays a key role in the processing of multi axis platforms.
4. Sensor technology: The sensor monitors the temperature, pressure, air pressure, distance between the laser head and the material and other factors during the processing to optimize the processing efficiency and improve the intelligent level. The sensor technology enables the laser to process curved and irregular surface materials, and realize the following machining, 3D machining and other difficult technologies, typically the overall cutting and welding of automobile sheet metal parts.
5. Hardware design technology: according to the needs of the laser industry, research and develop corresponding embedded software and hardware circuits, mainly for security and stability, such as equipment fault alarm, equipment security alarm, cooling system monitoring, software encryption, etc.
