Computer Numerical Control (CNC)

What is Computer Numerical Control (CNC)?
Computer Numerical Control (CNC) is a manufacturing method that automates the control, movement, and precision of machine tools through the use of preprogrammed computer software that is embedded within the tool.

CNC systems are commonly used in manufacturing to machine metal and plastic parts. Milling machines, lathes, routers, drills, grinders, water guns, and lasers are common cutting tools whose operations can also be automated with CNC systems. It can also be used to control non-mechanical tools such as welding, electronic assembly and wire winding machines.

How Computer Numerical Control Works
With a CNC system, each object to be manufactured has a customized computer program, usually written in an international standard language called G-code, stored in and executed by the machine control unit (MCU), which is attached to The machine's microcomputer. In CNC operations, the M code language is also used in conjunction with G code.

G-code controls the movement and functionality of the machine, while M-code controls the external movement of the operation. The program also contains instructions and parameters that the machine tool follows, such as the feed rate of the material and the positioning and speed of the tool components.

Early in the process, engineers create a computer-aided design (CAD) drawing of the part to be manufactured and then translate the drawing into G-code. The program is loaded onto the MCU and the machine operator performs a test run without raw material to ensure correct positioning and performance. This step is important because incorrect speed or positioning can damage the machine and parts.
When everything is ready, the CNC machine runs its program and completes the work exactly as directed. These jobs may involve creating something from scratch, to cutting workpieces or printing anything. Shenzhen Yujiaxin Technology Co., Ltd. uses high-precision metal CNC lathes to manufacture agricultural machinery parts, stainless steel mechanical engineering parts and anti-oxidation precision metal brass, aluminum and stainless steel parts. In-depth technical and engineering expertise from design and tooling to production and quality engineering. Our business model is to meet the mix of parts that global OEMs will source in China.
