CNC machining is a process of machining through computer-controlled numerical control machine tools, also known as numerical control machining. CNC stands for Computer Numerical Control, which is the automatic machining of machine tools controlled by computer programs, with high precision and repeatability. CNC machining has become an indispensable part of modern manufacturing, widely used in fields such as aerospace, automotive, shipbuilding, electronics, medical equipment, etc.

The advantages of CNC machining are mainly reflected in the following aspects: firstly, CNC machining can achieve the machining of complex parts. Through pre written machining programs, complex shapes such as curves and surfaces can be machined, which is more efficient than traditional machining methods; Secondly, CNC machining has high precision and repeatability, which can ensure the quality and accuracy of machined parts and reduce the impact of human factors on machining quality; Furthermore, CNC machining is suitable for mass production, which can significantly improve production efficiency and reduce costs.

In CNC machining, the main machine tools involved include CNC lathes, CNC milling machines, CNC grinders, CNC EDM machines, etc. These machine tools can control the movement of machining tools and the positioning of workpieces through computer programs, achieving the machining of various complex parts. In CNC machining, program writing is a crucial step. Programmers need to write machining programs based on the drawing and machining process of the part, determine parameters such as tool path, feed rate, cutting depth, etc., to ensure machining accuracy and efficiency.

In addition to machine tools and programming, various auxiliary equipment such as cutting tools, fixtures, and measuring devices are also required in CNC machining to ensure safety and accuracy during the machining process. At the same time, for the processing of some special materials or shapes, it is necessary to optimize cutting parameters and conduct process research to improve processing efficiency and reduce costs.

Overall, CNC machining has become an indispensable part of modern manufacturing, not only improving production efficiency and machining accuracy, but also promoting the transformation and upgrading of the manufacturing industry. With the continuous development and application of technology, CNC machining will become more intelligent and automated, bringing more opportunities and challenges to the development of the manufacturing industry.
