As an indispensable part of intelligent equipment manufacturing, laser cutting equipment is a high-end equipment integrating high technologies such as CNC technology, laser cutting technology, and inverter power supply technology. Among them, the CNC system plays a very important role.

Taking a laser cutting machine as an example, if it is compared to the human body, then the machine tool is its skeleton, the servo motor is its muscles, the laser is its heart, and the CNC system is its brain. This "brain" is the intermediate link between the user's design intentions and the mechanical communication.

It can be said that the performance of a laser cutting machine depends on the accuracy of its CNC system and the strong flexibility of its automatic control.

Laser Cutting Machine Numerical Control System Functions

The main function of the CNC system for laser cutting equipment is to input the processing path and process parameters, display and control the parameters in real time, and also perform interlocking, protection, and alarming of the actions of various components during processing.

Main Process Parameters of Laser Cutting Machine

According to the type of laser and processing method, the process parameters of different laser cutting equipment are different, and even have great differences. The main ones are as follows:

Laser Power

Focal Position

Processing Speed

Auxiliary Gas Pressure

Process Parameter Input Method

Control panel input. The input of relatively simple processing parameters is mainly carried out through the operation buttons on the control panel.

Specialized software input. The input of more complex processing parameters is mainly realized through specialized software. The interfaces of different laser cutting equipment and processing methods are also different.

Market Status and Development

With the widespread application of laser processing equipment, laser cutting CNC systems have also made great strides. In the low and medium power market, the proportion of domestically produced laser cutting CNC systems is very high, and it has shown a trend of completely replacing imports. Many local companies have made breakthroughs in this field.

Kudi II is one of the representatives. Focusing on the needs of the domestic market, Kudi II continues to innovate and develop, and successfully launched the first CNC system in China with completely independent intellectual property rights that can realize continuous blanking of metal coils in 2018—the LS100 laser dynamic continuous blanking CNC system.

The LS100 laser dynamic continuous blanking CNC system is a software platform specially developed for laser cutting, with the following characteristics:

High Reliability. The control bus uses a network-saving line method, which is convenient for installation and improves reliability.

High Flexibility 。 One axis, one card, simple and clear, highly interchangeable.

High Efficiency Rate 。 The communication bandwidth of the motion control equipment is as high as 20Mbps, which greatly improves processing efficiency.

Easy to operate. The system communication uses high-speed USB, and processing data can be imported from external devices and networks. Data can be transmitted quickly and securely, which is practical and convenient.

Safer 。 By combining software limit, sensor limit, and electromechanical limit, the safety performance is greatly improved.

Smoother 。 The speed control of the movement adopts the "automatic shifting" method to achieve perfect speed control. At the same time, using optimized motion trajectory planning ensures that the processing process is continuous and reliable.

LS100 has been successfully applied to Kudi II's laser continuous dynamic cutting machine, laser continuous blanking line and other equipment, and has been in normal service at the customer's factory for nearly two years. With good product performance and comprehensive cost performance, Kudi II's laser equipment has been widely praised by the market.

With more enterprises and talents investing in the research and development and production of laser technology, China's laser industry will accumulate greater potential and contribute to promoting China's industry to advance to a high-end level.
