What is CNC Machining? Definition Processes Components More

CNC machining refers to an umbrella of mechanical manufacturing methods and equipment, including milling (where material is cut by machine tools) and turning (which uses spinning stocks with an abrasive process to shape industrial components).

Manufacturers rely on computer-aided design (CAD) software to design products to specific technical requirements, while computer numerical control CNC Machining China use CNC g-code programming language to execute the plan. Manufacturers utilize computer aided design (CAD) software as part of the production process for creating their products according to personalized technical specs. Meanwhile, computer numerical control machine (CAM) software acts as an intermediary by translating CAD models into CNC machine language via G-Code translation software.


Computer numerical control (CNC) machining is a manufacturing technique in which pre-programmed computer software controls factory machinery and tools to craft custom parts with ease, eliminating manual operators altogether. CNC allows three-dimensional cutting without difficulty while eliminating human error from taking place during manual cutting operations.

CAD software produces 3D models which are uploaded to CAM software for interpretation and conversion into codes that the CNC machine understands, commonly referred to as G-code or M-code. Once this program runs on its own, all cuts and shaping of a part are completed as planned.

CNC machining is used extensively in the electronics industry for creating pins, casings and other components for electronic devices. CNC machines are also utilized by military to manufacture artillery pieces, missiles and fighter aircraft components that offer more accuracy and strength than many formative processes but may be more expensive for low volume orders and may impose design restrictions. Powder coating or silk screening finishes may be applied as aesthetic enhancements to CNC machined parts for aesthetic purposes.


CNC machining is a subtractive manufacturing process that removes layers of material from a blank (or workpiece) to produce custom parts, unlike additive manufacturing (such as 3D printing or liquid injection moulding).

Engineers use CAD software to design mechanical parts, which is then converted into G-code for loading into their machines for manufacturing operations without supervision.

CNC machining applications typically utilize metals and metal alloys, although plastics, foam, and composites can also be machined using the appropriate tooling. Each material requires specific techniques in order to be successfully machined.


5-axis machining refers to the ability of a CNC machine to move a part or cutting tool along five different axes simultaneously, enabling complex and precise cuts to be made.

Milling and sawing are among the most commonly employed machining operations, where material is removed with a blade. Other processes, like turning and polishing, sculpt stock into desired forms. Companies which utilize CNC machines often offer maintenance plans to ensure accurate performance as well as quality surface finish quality.


CNC machining is an inclusive manufacturing process that employs various machines and machine tools. Although the specific steps taken depend on what product is being created, all CNC machines use computer numerical control (CNC) programming movements for specific operations to produce custom-designed items.

CNC machining processes involve various cutting tool techniques that move across a workpiece surface to remove material, while others such as sawing, polishing and brushing may also be performed. Whatever operation type they utilize, all CNC machines rely on similar core components for proper functioning.

A CNC machine’s most essential element is the servo system, which plays an essential role in receiving and relaying CAM programs accurately to machine parts, enabling it to function without human interference and produce accurate results. Other key elements include the DPU and CLU, which ensure correct programming of CAM programs as well as eliminating errors during machine operation.


Computer software controls CNC machines so there is less human intervention, thus cutting production costs. Equipment can be programmed quickly and easily to produce products quickly in response to consumer needs; and machines require fewer technicians for operation and oversight, further cutting expenses.

Precision manufacturing techniques produce parts that look and work exactly as designed, which is particularly crucial for medical devices that must meet stringent specifications to avoid any detrimental health outcomes for patients.


CNC machining machine tools can handle various materials, including metals, plastics and composites. This versatility enables manufacturers to utilize this form of manufacturing in industries which demand precision and consistency such as the military or aerospace industries – for instance using CNC to design pins, casings and artillery components that defend troops and territories.
