What Is CNC Machining?

CNC (Computer Numerical Control) machining is a process using computer numerical control (CNC) machines, which are tools such as mills and lathes guided by computer instructions that control the precision of the instruments. A computer uses programming codes to direct machine tools to chip at (subtract) a material. This is until the material forms the input designed part.


This process is suitable for a wide range of materials, including metals, plastics, wood, glass, foam, and composites, and finds application in a variety of industries, such as large CNC machining, machining of parts and prototypes for telecommunications, and CNC machining parts, which require tighter tolerances than other industries.

Different machine tools can be controlled using computers. A number of tools, which include routers, grinders, mills, and lathes can be controlled by a CNC machine. A wide variety of machined parts can be produced by CNC machining technology. you can find several other common pieces of machinery used in CNC manufacturing to produce highly detailed and accurate CNC products. Some of the most common products produced by CNC machines include steel aerospace parts, metal automotive components, wooden decorations and plastic consumer goods pieces.


CNC machining enables the creation of parts and components that would usually be impossible to create manually. A single set of prompts fed into a computer can produce complex 3D products. The CNC machine removes material from the base stock piece through drilling, milling, turning or other types of operations to create shapes, angles and the finished product.


CNC Machining offers various options in terms of materials supported. You should know whether the material is compatible with the process before using it. Check for factors such as heat tolerance, sheer resistance, and hardness. You can say that choosing a material for CNC machining depends on the materials specifications and the manufacturing process. Examples of materials suitable for the process are: Aluminum; Copper; Brass; Stainless Steel; Titanium; Plastics.
