Computer numerical control (CNC) is a technology that uses a computer control system to control machine tools for machining operations. CNC machining can achieve high-precision, high-efficiency and repetitive machining, and is widely used in various fields of manufacturing.
The basic principle of CNC machining is to convert the designed CAD model or engineering drawings into instructions that can be recognized and executed by the machine tool through the computer control system, control the movement of the machine tool and the operation of the tool, and complete the processing process of the parts. The key to CNC machining is the CNC program, which describes information such as the movement trajectory of the machine tool, cutting parameters, and tool paths.

The main steps of CNC machining include the following aspects:
1.Design and modeling: Use CAD software to design and build 3D models or engineering drawings of parts.
2.Write the CNC program: according to the designed model or drawing, write the CNC program to describe the motion trajectory, cutting parameters and tool path of the machine tool.
3.Machining preparation: Load the CNC program into the control system of the CNC machine, set the machining parameters, and install and adjust the cutting tools.
4.Processing operation: start the CNC machine tool, control the control system in accordance with the instructions of the CNC program, control the machine tool to carry out processing operations, such as milling, turning, drilling, etc.
5.Processing monitoring and adjustment: During the processing process, monitor the processing status and quality, and make adjustments and corrections as needed to ensure the accuracy and quality of processing.
CNC machining has many advantages, including:
1.High precision: CNC machine tools can achieve high-precision processing to ensure the accuracy of the size and shape of the parts.
2.High efficiency: CNC machining can realize automation and continuous processing, improve production efficiency, and shorten the processing cycle.
3.Repeatability: CNC programs can be reused to ensure consistency and stability across multiple machining cycles.
4.Strong flexibility: By modifying the CNC program, the processing method and process parameters can be quickly changed to adapt to different processing needs.
CNC machining is widely used in the manufacturing industry, including aerospace, automobile manufacturing, electronic equipment, mold manufacturing and other fields. It improves production efficiency, reduces costs, and can realize the processing of complex shapes and structures to meet the requirements of different industries for part processing.
