Do you want to know the origin of machining? 

   -------Let's discuss it together.

The origin and development of CNC (Computer Numerical Control) machining parts are closely related to the automation and digitalization process of the manufacturing industry. 

1. Limitations of traditional machine tools

Before the mid-20th century, metal processing mainly relied on traditional manually operated machine tools (such as lathes and milling machines), which relied on the skills and experience of workers, and had problems such as low precision, poor efficiency, and difficulty in ensuring consistency.

2. The birth of numerical control technology (NC)

1952:MIT successfully developed the first three-axis CNC milling machine, which realized automated processing by inputting instructions through punched paper tape.

This NC machine tool still relies on hard-coded instructions and has limited flexibility.

3. Introduction of computer technology (CNC)

1960s~1970s:

With the development of computer technology, the numerical control system was upgraded to computer numerical control (CNC), and microcomputers replaced traditional circuit control.

1970s: CNC machine tools began to be commercially used, and complex geometric shapes were processed through programming (such as G code), greatly improving accuracy and efficiency.

4. Popularization of modern CNC machining parts

1980s~1990s:

Computer costs fell, CAD (computer-aided design)/CAM (computer-aided manufacturing) software matured, and CNC was seamlessly connected with the design end.

Multi-axis (five-axis, six-axis) CNC machine tools appeared, which can process more complex curved parts (such as impellers, aviation structural parts).

21st century:

CNC is combined with the Internet of Things (IoT) and artificial intelligence (AI) to achieve intelligent production (such as predictive maintenance and adaptive machining).

5. Core driving factors

Demand side: The demand for high-precision, small-batch customized parts in industries such as aerospace, automobiles, and medical care.

Technology side: Advances in computer technology, servo motors, sensors, etc.

Economic efficiency: Automation reduces labor costs and improves batch production consistency.

Today, CNC machining has become the cornerstone of modern manufacturing, and everything from precision medical devices to rocket engine components relies on its technology.
