In recent years, we have seen the rapid development of science and technology in our great motherland. This made me feel extremely proud for me as a Chinese. With the advancement of technology and the progress of people, we will join the Chinese cutting machine trading network to make progress together. Join the hotline, we look forward to your call.

The gantry CNC cutting machine control system plays a vital role in the cutting process and is the core component of the CNC cutting machine. What exactly does the CNC system do? Let's take a look at the contents of the CNC system today. There are eight main points:
1. Interpolation The task of interpolation is to perform "densification of data points" on the curve of a given starting point and end point. The interpolation program runs once in each interpolation cycle, and in each interpolation cycle, according to the instructions The feed rate calculates a tiny straight line data segment. In general, after a number of interpolation cycles, a block trajectory is completed after interpolation, and the "data point densification" operation from the beginning to the end of the block is completed.
2. Feed Rate Processing Speed ​​The first thing to do is to calculate the velocity of each motion coordinate according to the synthesis speed. In some CNC plasma cutting machine installations, restrictions on the minimum speed and maximum speed allowable for the machine tool and automatic acceleration/deceleration of the software are also handled in the CNC system.
3. Position control The main task of position control is to compare the theoretical position with the actual feedback position within each sampling period and use its difference to control the servo motor. The position control is on the position loop of the servo loop. This part of the work can be implemented by software or by hardware. In the position control, the position loop gain adjustment, pitch error compensation in each coordinate direction, and backlash compensation are usually performed to improve the positioning accuracy of the machine tool.
4. Display The display of the numerical control device is mainly for the convenience of the operator and is usually used for display of part programs, parameter display, tool position display, machine tool status display, and alarm display.
5, the input part program and control parameters, compensation and other data input, can use optical reader, keyboard, disk, connect to the upper computer DNC interface, network and other forms. In the input process, the numerical control device usually completes the work of deleting the invalid code, checking the code, and transcoding the code.
6. Decoding Regardless of whether the system is working in MDI mode or memory mode, the part program is processed in units of one block, and various parts of the profile information (such as starting point, end point, straight line or arc, etc.) and processing are processed. The speed information and other auxiliary information are interpreted according to certain grammatical rules into a language that the computer can recognize, and stored in a specified memory dedicated unit in a certain data format.
7. Tool compensation Tool compensation includes length compensation and radius compensation. Usually the part program of the numerical control device is programmed with the part contour trajectory, and the tool compensation function is to convert the part contour trajectory into the tool center trajectory. At present, in a better numerical control device, the tool-compensated workpiece also includes automatic transfer and over-cutting discrimination between program segments.
8. Diagnosis Checks and locates abnormal conditions in the system, including online diagnostics and offline diagnostics.
These eight points are the daily work contents of the gantry type CNC flame cutting machine control system. It can be seen that the numerical control system does have an important role in the cutting process and therefore must be understood.
