Computer numerical control (CNC) machining was invented more than 50 years ago, and since then, its high precision and automation capacity has helped create countless products. Across industries, from defense, automotive and aerospace to medical, precision and manufacturing, this sophisticated technology has become part of the world's industrial DNA.
In traditional machining, a skilled machinist operates a machine, removing or forming metal. This is done according to specifications provided by designers and engineers, usually through an engineering blueprint or drawing. They use rotating wheels, dials, switches, chucks, jaws, and a variety of cutting tools made from hardened steel, carbide, and industrial diamond and then use measuring instruments to make sure all dimensions are correct.
The CNC machining They perform the same function as traditional machining (metal cutting, drilling, milling, boring, grinding, and other metal forming and removal functions), but use computer numerical control instead of manual control by a machinist. It is almost as precise the first time cutting as the last time on a piece.
CNC machining: its uses
The CNC machining They are widely used in digital manufacturing and sometimes in low-volume production runs, as the CNC machining They can be reviewed and modified for modifications and different materials. This type of machining is much more precise and has largely replaced traditional machining in manufacturing and industrial production.
Specifically, computer numerical control uses Cartesian coordinates. These are spatial coordinates, in various dimensions, using coordinates and axes. Machine automation controls your cutting, boring, drilling or other operation using the numerical control of a computer that reads the coordinates. These coordinates were designated by engineers in the digital drawing and design of the product.
The CNC machining They use subtractive processes, meaning that raw material is machined to its final shape by subtracting and removing material. Holes are drilled, batches are drilled, and metal material is molded into new materials with different tapers, diameters, and shapes. For subtractive manufacturing, shapes are achieved by subtracting material. This contrasts with other types of processes, such as additive manufacturing, where materials are added, layered and deformed into a specific shape. It also contrasts with injection molding, where the material is injected into a different state of matter, using a mold, and given a specific shape.
This versatility has helped CNC machining They are a popular choice across industries, allowing designers and engineers to manufacture products with efficiency and precision.
