CNC controller is a program control system of computer numerical control machine tools
1. Definition and core functions of CNC controller
The CNC controller is the core component of the Computer Numerical Control (CNC) machine tool, which is responsible for the logical processing of programs with control codes or other symbolic instructions. It decodes instructions through a computer and controls the machine tool to perform the prescribed actions, so as to process the blank into semi-finished or finished parts. This process significantly increases the productivity of mold processing.

2. The main functions of the CNC controller
The functions of CNC controllers are usually divided into basic functions and selection functions, which mainly include the following aspects:

Axis control function: Controls the number of axes of the machine, including moving axes and rotary axes. For example, CNC lathes usually require 2 axes to control at the same time, while machining centers may require 3 or more.
Preparation function (G function): Command the movement mode of the machine tool, including basic movement, plane selection, coordinate setting, etc.
Interpolation function: The trajectory of the tool movement is realized through software interpolation, which is divided into coarse interpolation and fine interpolation to ensure machining accuracy and efficiency.
Feed function: According to the requirements of the machining process, directly command the feed speed of each axis.
3. The application and significance of CNC controller
CNC controllers are widely used in CNC machine tools, such as CNC lathes, CNC milling machines, machining centers, etc. It realizes automatic processing through program control, which not only improves production efficiency, but also ensures machining accuracy and consistency. In addition, the multi-axis linkage function of the CNC controller enables it to handle the machining of parts with complex shapes, further expanding its range of applications.

4. Technical characteristics of CNC controller
A CNC controller is essentially a dedicated, real-time multitasking computer system capable of efficiently handling complex machining instructions. Its hardware and software architecture is optimized to meet the real-time and accuracy requirements of CNC machine tools.

Through the above analysis, it can be seen that CNC controller is an indispensable core technology in modern manufacturing, and its function and application are of great significance to improve production efficiency and processing quality.
