Laser motion control system is located in the upstream group of the whole industry. Through the integration of key technologies such as computer-aided design technology, numerical control technology and computer manufacturing, it covers all aspects related to laser processing such as typesetting, feeding, cutting and welding. It provides a complete system solution to ensure the good operation of all links. It is an essential component for the normal operation of laser equipment.

The main application scenarios of 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, many indexes such as laser precision, efficiency and stability depend on the real-time instructions of the motion control system. Therefore, it is very important to select an appropriate control system.

Back to the laser motion control system, its core technology mainly includes the following five aspects:
1. Computer aided design technology: through computer modeling or reading the processing model from external files, carry out graphic recognition, editing and optimization, typesetting on the processing materials, and output the model to be processed.
2. Computer aided manufacturing technology: after completing the input of processing model, output laser processing instructions according to 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 machining path is optimized, the drilling position is set, and the machining 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, cooperate with the laser output instructions to complete the specific operation of laser processing, and play a key role in the processing of multi axis platform.
4. Sensor technology: through the sensor to monitor the temperature, pressure, air pressure, the distance between the laser head and the material and other factors in the processing process, optimize the processing efficiency and improve the intelligent level. Sensor technology enables laser to process curved and irregular surface materials, and realize highly difficult technologies such as follow-up processing and three-dimensional processing. The typical example is the overall cutting and welding of automobile sheet metal parts.
5. Hardware design technology: according to the needs of the laser industry, develop corresponding embedded software and hardware circuits, mainly for security and stability, such as equipment fault alarm, equipment safety alarm, cooling system monitoring, software encryption, etc. Domestic laser control system manufacturers are mainly concentrated in the field of low and medium power. Becchu electronics, Weihong shares and orsendico occupy most of the market share. In the subdivided field, there are also many head players. For example, the motion control system of Ruida technology is in the leading position in the field of low and medium power CO2 laser equipment. In terms of medium and high power, Siemens, German Beifu and other foreign enterprises have advantages.
At present, laser processing is constantly expanding its territory in high-end manufacturing industries such as 5g communication, chip manufacturing, curved screen, photovoltaic, precision parts processing and new energy vehicles. It is one of the most dynamic processing technologies in the new generation.
