What is CNC machining?

CNC machining refers to the application of Computer Numerical Control (CNC) technology to the process of machining. Here CNC machines are used to control cutting tools, such as milling, turning and drilling tools, and remove materials with high precision to obtain specific shapes, dimensions and surface characteristics.

What does CNC stand for?

CNC stands for “Computer Numerical Control” and refers to an automated technology used to control machines and tools in the manufacturing industry. CNC machines are capable of performing precise operations on materials such as metal, plastic, wood and more, based on digital instructions entered through a computer program.

Instead of manual control by an operator, a CNC machine uses a series of programmed instructions to perform movements and operations. These instructions are often generated using special software known as “CAM software” (Computer-Aided Manufacturing). The machine interprets the instructions and performs precision movements, such as cutting, drilling, milling and turning, to produce complex parts and products.

What is machining?

Machining refers to the process of shaping and machining material by removing excess material. This is usually done using cutting tools, such as chisels, cutters, drills and turning tools, which contact the workpiece and remove material to achieve the desired shape, dimensions and surface quality.

Machining is often applied to materials such as metal, plastic, wood and composites. The purpose of machining is to produce parts, components or products with specific geometric characteristics and tolerances. This process is often used in the manufacturing industry to produce precise and complex parts that meet the requirements of designs and technical specifications.

The advantages of CNC machining

Especially in the manufacturing industry, CNC machining offers useful advantages that ensure better effectiveness in a more efficient way.

• Accuracy: CNC machines can perform complex operations with high precision, resulting in consistently high-quality products.
• Automation: The automated nature of CNC machines allows for long-term autonomous operations, reducing the need for constant manual supervision.
• Complexity: CNC machines can process complex shapes and patterns with ease, which is often difficult or impossible with manual machining.
• Efficiency: CNC machines can speed up processes and reduce waste, leading to lower production costs and faster lead times.
• Reproducibility: The same CNC programs can be used repeatedly to produce identical products, ensuring consistent results.
